Hey,
I'm getting different answers when I perform the same integration but by just expanding the squared term.
How is this possible?
As I procced further, I'm getting 2 completely different answers as my result.
Which one is correct?
PS: I'm getting the same answer even after using 'IgnoreAnalyticConstraints',true.
Thanks

They are not the same expressions.
syms x
int((1+cos(x))^2,0,pi)
int(1+2*cos(x)+cos(x)^2,0,pi)
int(1+cos(x)^2-2*(1-cos(x)),0,pi)%this is not the same expression

Look up the binomial formula:
(a-b)^2 = a^2 - 2*a*b + b^2
