Category: Lisp Core  Integration Group: None >Status: Closed >Resolution: Fixed Priority: 5 Private: No Submitted By: Dieter Kaiser (crategus) Assigned to: Nobody/Anonymous (nobody) Summary: Laplace transform of asin or atan gives wrong noun form Initial Comment: The routine $specint does not give the correct noun forms for integrands with the asin or atan function. (%i2) assume(s>0)$ In the results the function is missing: (%i5) specint(exp(s*t)*asin(t),t); (%o5) ?%specint(%e^(s*t),t) (%i6) specint(exp(s*t)*atan(t),t); (%o6) ?%specint(%e^(s*t),t) If we look at the algorithm of the Laplace transform for the hypergeometric function, we can expect a result for both functions when the argument is 1/sqrt(t). But we do not get a result. The noun form is wrong too.

Category: Lisp Core  Solving equations Group: None Status: Open Resolution: None Priority: 5 Private: No Submitted By: Nobody/Anonymous (nobody) Assigned to: Nobody/Anonymous (nobody) Summary: to_poly_solve gives too many solutions Initial Comment: Instead of as in Maxima 5.16.3, where we correctly get: to_poly_solve(Q*sqrt(Q^2+2)1,Q); [Q=1/sqrt(sqrt(2)+1), Q=1/sqrt((sqrt(2)+1)] in 5.19.1, we get the 1 versions, but: a:1/sqrt(sqrt(2)+1); b:bfloat(a); b*sqrt(b^2+2)1; 2.0b0 so presumably the negative ones are spurious.
