The commands plot2d and plot3d are working. But maxima everytime produces a file maxout.gnuplot and leaves it on my desktop. What can i do? Besides i´ve got another question: I installed gnuplot before maxima. Does maxima find my "old" gnuplot or have i got to use the gnuplot that comes with maxima ?

"Division by 0" is strange. The definite integral below is certainly greater than 0 as the integrand is positive over [0, 1]. "integrate (1/((x3)^4+1/2), x)" returns the noun form, so maybe (maybe) what happens is that the noun form is evaluated at the limits of integration and it's the same, hence 0 is the result. (Just guessing there.) Note that the difference between the two integrands is that one is 1/(something + 1), while the other is 1/(same something + 1/2).  (%i1) integrate (1/((x3)^4+1), x, 0, 1); Division by 0  an error. Quitting.

Fixed by setting the 'algebraic' flag: integrate (1/((x3)^4+1), x, 0, 1),algebraic:true For the indefinite integral, you can factor over the Gaussians then use partfrac: integrate ( partfrac ( gfactor( 1/((x3)^4+1) ), x ), x ) You can simplify the result using ratsimp(rectform(...)) s  Comment By: Nobody/Anonymous (nobody) Date: 20050118 16:17 Message: Logged In: NO Two remarks: The method that Maxima uses to solve such integrals is integration by residues. Trace (residue) shows that this function is called with the correct arguments but answers zeroes for integrate (1/((x3)^4+1/2), x, 0, 1); and runs into a division by zero for the other integral. The indefinite integrals can be solved with changevar: 'Integrate(1/((x3)^4+1/2), x); changevar (%, x  3  y ,y ,x); ev (%, Integrate);  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1073338&group_id=4933

Initial Comment: nroots claims that 1 isn't a univariate polynomial, and that sqrt(3) is. This is chaotic. Further, nroots(%pi,minf,inf) > 1, nroots(sqrt(3),minf,inf) > 1. These are both wrong. It's not clear from the documentation, but it seems that nroots does not allow algebraic coefficients; if that's the case, the documentation should say so. Finally, nroots counts multiplicities, but the user documentation doesn't say that it does. (%i1) nroots(1,minf,inf); Argument must be a univariate polynomial  an error. Quitting. To debug this try DEBUGMODE (TRUE); (%i2) nroots(sqrt(3),minf,inf); (%o2) 1 (%i3) nroots(%pi,minf,inf); (%o3) 1 (%i4) nroots(sqrt(3)*x+sqrt(7)); Argument must be a univariate polynomial  an error.

As for excluding algebraic coefficients.... I agree that this should be documented. The method (Sturm sequences) is exact for exact evaluation of polynomials. Exact evaluation is easy for rational coefficients. The result is approximate for approximate coefficients (floats), which is also fine. However, though algebraic numbers are exact, calculating with them exactly is a problem. If this matters to you, I suppose you can use increasingly precise intervals until the signs are unambiguous (though checking for 0 is harder...), but Maxima doesn't currently support interval arithmetic. Anyway, what I would suggest is not changing the documentation, but instead converting algebraic numbers to rationals (at what precision?) and giving the warning: Warning: nroots will not always give exact results with nonrational coefficients Unfortunately, nroots does not currently support bfloats....

It's not clear from the documentation, but it seems that nroots does not allow algebraic coefficients; if that's the case, the documentation should say so.

Bugs item #1079521, was opened at 20041205 12:19 Message generated for change (Settings changed) made by robert_dodier You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1079521&group_id=4933 Category: Lisp Core Group: None >Status: Closed >Resolution: Wont Fix Priority: 2 Submitted By: Robert Dodier (robert_dodier) Assigned to: Nobody/Anonymous (nobody) Summary: freeof (exp, exp(x)) yields true Initial Comment: freeof (exp, exp(x)) => true although freeof (sin, sin(x)) => false (kill (f), freeof (f, f(x))) => false Exponentials are always stored as %e^something, so freeof (%e, exp(x)) => false Dunno what is the right policy here. Substituting %e for exp in the argument list (which is consistent with the otherwise universal policy of substituting %e^x for exp(x)) won't work right: freeof (exp, exp(x)) hypothetically => false (OK) freeof (exp, %e*2) hypothetically => false (OOPS) Another answer is to not substitute %e^x for exp(x) but that will have widespread effects (to put it mildly).  >Comment By: Robert Dodier (robert_dodier) Date: 20050124 17:14 Message: Logged In: YES user_id=501686 Based on comments from Stavros, I'm closing this as a nonbug; the observed effect is a consequence of simplification. I'll add something about the effect of simplification to the freeof description.  Comment By: Stavros Macrakis (macrakis) Date: 20050124 15:42 Message: Logged In: YES user_id=588346 This is not a freeof issue. It is not that exponentials are "stored as" %e^x, it is that the expression exp(x) is simplified to %e^x. The function 'exp' just never appears in a simplified expression. Similarly sin(%i) simplifies to %i*sinh(1). Surely you don't expect freeof to "find" the sin in %i*sinh(1) or to "find" the exp in 2^n (which is precisely equivalent to exp(n*log(2)). Of course, Maxima is not completely consistent about when it canonicalizes and when it does not (even when this is feasible). For example, by default it does *not* simplify exp(n*log(2)) to 2^n, but to %e^(log(2)*n); it does not simplify n! to gamma(n+1); etc.  You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1079521&group_id=4933

Bugs item #1094108, was opened at 20050101 12:04 Message generated for change (Comment added) made by macrakis You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=104933&aid=1094108&group_id=4933 Category: None Group: None Status: Open Resolution: None Priority: 5 Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: Maxima crashed Dell 8400 Initial Comment: I installed Maxima on two dells for trial runs: Dell 8400 (P4, 3.2GHz) and Dell Latitude C610 (P3, 1.2 GHz). All installed tests cases run and my simple tests also work. Maxima is granted with full network access in firewall setting. And Maxima is brought up in the startup as installed. Dell 8400 has multiple user setup. When the machine is idled, sometime the machine will freeze. When the user switched, the machine always froze. I uninstalled Maxima on Dell 8400. Everything else function properly.  >Comment By: Stavros Macrakis (macrakis) Date: 20050124 17:29 Message: Logged In: YES user_id=588346 What version of Maxima (use bug_report() for configuration information)? What operating system and version on each computer? What firewall? What exactly do you mean by "when the user switched"?
