I got this expression:

a / ( a2*sin(t)2 + cos(t)2 )

Is there any way to reduce it using some identity?

What is sin(t)2 + cos(t)2 ?

Does that really matter, though? We're not dealing with sin^2(t)+cos^2(t). We're dealing with (a sin(t))^2 + cos^2(t).

True, just trying a few things. Can we factor the bottom to give (sin2t + cos2t) x something? Might be useful, might not

Well, I don't know if it helps, but I managed to factor it to this:

[tex]\frac{a}{\left(a^2-1\right)sin^2(t) + 1}[/tex]

That's the best I can do though.
