Description
(this was reported as part of #6882)
... solving of ode y'=c*x is not correct, the free variable is messed up with a parameter, see sage-devel - thanks for Yuri Karadzhov
sage: from sage.calculus.calculus import symbolic_expression_from_maxima_string
sage: symbolic_expression_from_maxima_string('%c')
c
sage: c=var('c'); y=function('y',x); eq=diff(y,x)==c*x; eq
D[0](y)(x) == c*x
sage: desolve(eq,y,ivar=x)
1/2*c*x^2 + c
the answer should be something like 1/2cx2 + c1
The fix depends on closing #8734. The c variable that comes from Sage can then be easily recognized, and the constant c should then be renamed to c1 or _C1.
Depends on #8734
