Mathcad simplify tool ->Sin(t)^2+Cos(t)^2

I am a beginner. When I try to solve a  differential equation problem, the "simplify" tool can not recognize the Sin(t)^2+Cos(t)^2=1. I have to simplify the equation manually.

 

The attach file shows how I do this now. Is there a solution that Mathcad can handle the identity relation Sin(t)^2+Cos(t)^2=1.?
