Hi i'm currently on Trigonometric equations.

I got stuck on one particular math problem.

It's the following problem

Sin(x*pi/2)=cos(x*pi/2)+1

-2<= x <=2

I have tried over and over again but i can't solve it...

so if some kind sperit could give me some input on how to solve it, and what method to use it would be nice

Sorry for my bad english....

and thank you in advance
