You're going to have to be a little more specific, what are u and v? Are you looking to simplify this expression? As well, when you preview a post it adds the template to your post again, so remember to delete it.

Hello! Use cos(A+B)=cosAcosB-sinAsinB

Then, use:
cos[arcsin(x)]=√1-x²
sin[arccos(x)]=√1-x²
