Hi.

Can anyone help me find the angles (values of t) where:

25*sin(t) = 22*sin(2t) - 18*cos(2t)

I know the general way to do it is to get all one trig function and form a quadratic then solve it, but I'm not too hot on the identities and I can't seem to get rid of the double angle bits and make everything sine or anything like that!

Help!

Thanks!
