trigonometric identity s2+c2=1
by Dario Pellegrini 19 Jul '19

I noticed that GiNaC does not apply the simplification: cos(x)^2+sin(x)^2 = 1 for any x in R Is there any way for me to force this substitution in my expressions? That would greatly simplify them...

fsolve system of equation
by Dario Pellegrini 19 Jul '19

Hi all. I have a bidimensional system of two nonlinear equations (containing some trigonometric functions) which I would like to solve numerically. I spent few hours searching for an example but I could not find any. Is it possible to achieve this within the GiNaC framework?
