!   
!   You should type in your answers using the same syntax used in the
!   symbolic mathematics package, known as a computer algebra system
!   (cas), underpinning your implementation.  This could be
!   either <i>Axiom</i> or  <i>Maxima</i>.  The syntax is broadly similar
!   to the syntax used for mathematical formulae in general programming
!   languages such as Java, C and Basic and in spreadsheet programs such
!   as Excel, so you will find it useful to master it.  If you are
!   taking the Applied Mathematics Core course AMA101 then you will
!   learn to use such a system there.  If you are not, the advice below should
!   be sufficient.  Stack tries quite hard to give helpful information 
!   about syntax errors.  You can also learn about the right syntax by
!   doing tests in practice mode and asking for
!   the solutions; as well as displaying the right answers in ordinary
!   mathematical notation, Stack will tell you how they could be
!   entered.  (However, there are often several possible ways, and Stack
!   will not always suggest the easiest one.)
!   <br /><br />
!   When you have entered your answer, you can always click on the
!   <b>Validate</b> button at the bottom of the page to see how the CAS will
!   interpret it.  If there are any syntax errors or the cas has
!   misunderstood what you meant then you can fix the problem before
!   asking Stack to mark your work.
! 
!   <ul>
!    <li> Numbers like <font color="BLUE">1/4</font> should be entered as
!     <tt><font color="GREEN">1/4</font></tt>, not as 
!     <tt><font color="GREEN">0.25</font></tt>, which can cause some
!     subtle problems.
!    </li>
!    <li> Use a star for multiplication: for example,
!     <font color="BLUE">3x</font>  should be
!     entered as <tt><font color="GREEN">3*x</font></tt>.  Forgetting this
!     is by far the most 
!     common source of syntax errors.  Note that you do <b>not</b> need
!     a semicolon at the end, unlike when you are using a CAS directly.
!    <br /><br /></li>
!    <li> Use a caret (^) for raising something to a power: for example,
!     <font color="BLUE">x<sup>2</sup></font> should be entered as
!     <tt><font color="GREEN">x^2</font></tt>.  You can get
!     a caret by holding down the SHIFT key and pressing the 6 key
!     on most keyboards.  Negative or fractional powers need brackets:
!     enter <font color="BLUE">x<sup>-2</sup></font> as
!     <tt><font color="GREEN">x^(-2)</font></tt>
!     and <font color="BLUE">x<sup>1/3</sup></font> as
!     <tt><font color="GREEN">x^(1/3)</font></tt>.
!    <br /><br /></li>
!    <li> More generally, when in doubt, use brackets.  For example, 
!     <font color="BLUE">
!     <center><table border="0" align="center"><tbody><tr><td>
!     <table align="left"><tbody><tr><td nowrap="nowrap" align="center">
!     </td><td nowrap="nowrap" align="center">
!      a + b<hr noshade="noshade">
!      c + d <br /></td><td nowrap="nowrap" align="center">
!     </td></tr></tbody></table>
!     </td></tr></tbody></table></center>
!     </font>
!     should be entered as
!     <tt><font color="GREEN">(a+b)/(c+d)</font></tt>.  
!     Note that in this context you should always use ordinary round
!     bracket (like <tt><font color="GREEN">(a+b)</font></tt>), not
!     square or curly ones (like <tt><font color="GREEN">[a+b]</font></tt>
!     or <tt><font color="GREEN">{a+b}</font></tt>).
!     <br />
!     If you type 
!     <tt><font color="GREEN">a+b/(c+d)</font></tt>, then Stack
!     will think that you mean 
!     <font color="BLUE">
!     <center><table border="0" align="center"><tbody><tr><td>
!     <table align="left"><tbody><tr><td nowrap="nowrap" align="center">
!      a +</td><td nowrap="nowrap" align="center">
!     b<hr noshade="noshade">
!      c + d<br /></td><td nowrap="nowrap" align="center">
!     </td></tr></tbody></table>
!     </td></tr></tbody></table></center>
!     </font>
!     If you type <tt><font color="GREEN">(a+b)/c+d</font></tt>, then Stack
!     will think that you mean  
!     <font color="BLUE">
!     <center><table border="0" align="center"><tbody><tr><td>
!     <table align="left"><tbody><tr><td nowrap="nowrap" align="center">
!     </td><td nowrap="nowrap" align="center">
!     a + b<hr noshade="noshade">
!      c<br /></td><td nowrap="nowrap" align="center">
!     + d </td></tr></tbody></table>
!     </td></tr></tbody></table></center>
!     </font>
!     If you type <tt><font color="GREEN">a+b/c+d</font></tt>, then Stack
!     will think that you mean 
!     <font color="BLUE">
!     <center><table border="0" align="center"><tbody><tr><td>
!     <table align="left"><tbody><tr><td nowrap="nowrap" align="center">
!      a +</td><td nowrap="nowrap" align="center">

!      c<br /></td><td nowrap="nowrap" align="center">
!     + d </td></tr></tbody></table>
!     </td></tr></tbody></table></center>
!     </font>
!     <br />
!     Some other examples:
!     <ul>
!      <li>
!       <font color="BLUE">2<sup>a+b</sup></font> should be entered as
!       <tt><font color="GREEN">2^(a+b)</font></tt>
!      </li>
!      <li>
!       <font color="BLUE">2 cos 3x</font> should be entered as
!       <tt><font color="GREEN">2*cos(3*x)</font></tt>
!      </li>
!      <li>
!       <font color="BLUE">e<sup>ax</sup>sin(bx)</font> should be entered as
!       <tt><font color="GREEN">exp(a*x)*sin(b*x)</font></tt> 
!      </li>
!      <li>
!       <font color="BLUE">(a x<sup>2</sup> + b x + c)<sup>-1</sup></font>
!       should be entered as
!       <tt><font color="GREEN">(a*x^2 + b*x + c)^(-1)</font></tt>.
!      </li>
!     </ul>   
!    <br /><br /></li> 
!    <li>the CAS system is case-sensitive.  Do not enter 
!     <tt><font color="GREEN">X</font></tt> instead of
!     <tt><font color="GREEN">x</font></tt>, or 
!     <tt><font color="GREEN">a</font></tt> instead of
!     <tt><font color="GREEN">A</font></tt>, or
!     <tt><font color="GREEN">Log(Z)</font></tt> instead of
!     <tt><font color="GREEN">log(z)</font></tt>.
!    </li>
!    <li>The absolute value of <font color="BLUE">x</font>, which is
!     written as <font color="BLUE">|x|</font> in traditional notation,
!     must be entered as <tt><font color="GREEN">abs(x)</font></tt>.
!    </li>
!    <li>
!     Standard functions such as sin, cos, tan, exp, log and so on can
!     be entered using their usual names.  However, the argument must
!     <font color="RED">always</font> be enclosed in brackets:
!     <font color="BLUE">sin x</font> should be entered as 
!     <tt><font color="GREEN">sin(x)</font></tt>,
!     <font color="BLUE">ln 3</font> should be entered as
!     <tt><font color="GREEN">ln(3)</font></tt> and so on.  You can use
!     either <tt><font color="GREEN">log(x)</font></tt> or
!     <tt><font color="GREEN">ln(x)</font></tt> for
!     the natural logarithm of x (note that both of these start with a
!     lower case l, not a capital I).  The function
!     <font color="BLUE">1/sin(x)</font> must be
!     referred to as <tt><font color="GREEN">csc(x)</font></tt> rather
!     than <tt><font color="GREEN">cosec(x)</font></tt> (or you can just call
!     it <tt><font color="GREEN">1/sin(x)</font></tt> if you prefer).  You
!     should always write 
!     <tt><font color="GREEN">exp(x)</font></tt> for 
!     <font color="BLUE">e<sup>x</sup></font>.
!    <br /><br /></li>
!    <li>
!     <font color="BLUE">sin<sup>2</sup>x</font> should be entered as
!     <tt><font color="GREEN">sin(x)^2</font></tt> (which is
!     what it really means, after all).  Similarly for
!     <font color="BLUE">tan<sup>2</sup>(x)</font>, 
!     <font color="BLUE">sinh<sup>2</sup>(x)</font> and so on.
!    <br /><br /></li>
!    <li>
!     Recall that <font color="BLUE">sin<sup>-1</sup>(x)</font>
!     traditionally means the number <font color="BLUE">t</font> such that
!     <font color="BLUE">sin(t) = x</font>, which is of
!     course completely different from the number
!     <font color="BLUE">sin(x)<sup>-1</sup> = 1/sin(x)</font>.  This
!     traditional notation is really rather unfortunate and is not used
!     by the CAS; instead, <font color="BLUE">sin<sup>-1</sup>(x)</font>
!     should be entered as <tt><font color="GREEN">arcsin(x)</font></tt>.
!     Similarly, <font color="BLUE">tan<sup>-1</sup>(x)</font> should be 
!     entered as <tt><font color="GREEN">arctan(x)</font></tt> and so on.
!    <br /><br /></li>
!    <li>
!     Greek letters can be entered using their English names: for
!     example, enter 
!     <font face="SYMBOL" color="BLUE">a+b</font>
!     as <tt><font color="GREEN">alpha+beta</font></tt>, and
!     <font face="SYMBOL" color="BLUE">2p</font>
!     as <tt><font color="GREEN">2*pi</font></tt>.
!    <br /><br /></li>
!    <li>
!     When you work directly with a CAS, the vector <font color="BLUE">(1,2,3)</font> must be entered as 
!     <tt><font color="GREEN">vector([1,2,3])</font></tt>.  Many Stack
!     questions are set up so that you can just enter <tt><font color="green">[1,2,3]</font></tt> instead.
!    </li>
!    <li>
!     When you work directly with a CAS, the matrix
! <font color="BLUE">

!     <tt><font color="GREEN">sin(x)</font></tt>,
! 
!     <font color="BLUE">ln 3</font> should be entered as
! 
!     <tt><font color="GREEN">ln(3)</font></tt> and so on.  You can use
! 
!     either <tt><font color="GREEN">log(x)</font></tt> or
! 
!     <tt><font color="GREEN">ln(x)</font></tt> for
! 
!     the natural logarithm of x (note that both of these start with a
! 
!     lower case l, not a capital I).  The function
! 
!     <font color="BLUE">1/sin(x)</font> must be
! 
!     referred to as <tt><font color="GREEN">csc(x)</font></tt> rather
! 
!     than <tt><font color="GREEN">cosec(x)</font></tt> (or you can just call
! 
!     it <tt><font color="GREEN">1/sin(x)</font></tt> if you prefer).  You
! 
!     should always write 
! 
!     <tt><font color="GREEN">exp(x)</font></tt> for 
! 
!     <font color="BLUE">e<sup>x</sup></font>.

! 
!     <tt><font color="GREEN">sin(x)^2</font></tt> (which is
! 
!     what it really means, after all).  Similarly for
! 
!     <font color="BLUE">tan<sup>2</sup>(x)</font>, 
! 
!     <font color="BLUE">sinh<sup>2</sup>(x)</font> and so on.
!

!

! 
!     Recall that <font color="BLUE">sin<sup>-1</sup>(x)</font>
! 
!     traditionally means the number <font color="BLUE">t</font> such that
! 
!     <font color="BLUE">sin(t) = x</font>, which is of
! 
!     course completely different from the number
! 
!     <font color="BLUE">sin(x)<sup>-1</sup> = 1/sin(x)</font>.  This
! 
!     traditional notation is really rather unfortunate and is not used
! 
!     by the CAS; instead, <font color="BLUE">sin<sup>-1</sup>(x)</font>
! 
!     should be entered as <tt><font color="GREEN">arcsin(x)</font></tt>.
! 
!     Similarly, <font color="BLUE">tan<sup>-1</sup>(x)</font> should be 
! 
!     entered as <tt><font color="GREEN">arctan(x)</font></tt> and so on.
! 
!    <br /><br /></li>
! 
!    <li>
! 
!     Greek letters can be entered using their English names: for
! 
!     example, enter 
! 
!     <font face="SYMBOL" color="BLUE">a+b</font>
! 
!     as <tt><font color="GREEN">alpha+beta</font></tt>, and
! 
!     <font face="SYMBOL" color="BLUE">2p</font>
!

! 
!    <br /><br /></li>
! 
!    <li>
! 
!     When you work directly with a CAS, the vector <font color="BLUE">(1,2,3)</font> must be entered as 
! 
!     <tt><font color="GREEN">vector([1,2,3])</font></tt>.  Many Stack
! 
!     questions are set up so that you can just enter <tt><font color="green">[1,2,3]</font></tt> instead.

! <p>It is also possible to define functions within the Question 
! 
! Variables for use within a question.  This is not recommended, 
! 
! and has not been widely tested. For example 
! 
!  <pre>dum1 = f(x) := x^2 
! 
! n = f(4)</pre> Again, the syntax requires this to be of the form 
! 
! <tt>key = value</tt>, so that another dummy assignment has taken 
! 
! place. Please look at Maxima's documentation for <?php         
! 
!  $url = $stack_web_url."maximadocs/maxdoc/maxima_39.html#SEC120";
!
