*Hello
I don't know if this is the right place to report a bug...
wxMaxima 0.7.1
Maxima 5.10.0
Using Lisp GNU Common Lisp (GCL) GCL 2.6.7 (aka GCL)
I've done:
depends([r, phi], t)
And then, while doing manipulations I get:
(%i47) ratsimp(%);
(%o47)
matrix([cos(phi)*('diff(r,t,1))-sin(phi)*('diff(phi,t,1))*r],[sin(phi)*('diff(r,t,1))+cos(phi)*('diff(phi,t,1))*r])=matrix([(-cos(phi)*sin(phi)^2-cos(phi)^3)*r^3+(sin(phi)+cos(phi))*r],[(-sin(phi)^3-cos(phi)^2*sin(phi))*r^3+(sin(phi)-cos(phi))*r])
(%i48) trigsimp(%);The argument to put must be a symbolic
name:'diff(sin,t,1)#0:
trigsimp(?_l=[matrix([cos(phi)*'diff(r,t,1)-sin(phi)*'diff(phi,t,1)*r],[sin(phi)*'diff(r,t,1)+cos(phi)*'diff(phi,...)
-- an error. Quitting. To debug this try debugmode(true);
Thanks
Ismael
