Hello,

I have an expression y, it comes from a calculation. I would like to simplify the argument of arctan in the expression using Maple. (This can be a part of a complicated expression, so I 'd like to automatize this procedure).

Assumptions: s0>0, w>0

y:=cos(w*t-arctan(2*s0^3*w, -s0^2*(-s0^2+w^2)));
 

Thank you for your help in advance.
