In the first one, take out as a factor, what do you get?
For the second, create a quadratic using what do you get?
These are the problems I have trouble with while doing a practice on this topic.
1. Factor the expression and use fundamental identities to simplify:
cos^(2)x csc^(2)x - cos^(2)x
2. Find all solutions in the interval [0 , 2pi)
tan^(2)θ = (-3/2)secθ
3. Find an expression that completes the identity
[2sin^(2)x + cos(2x)] / csc(x) =
It would be helpful if u could explain step by step. I'm not just looking for answers. Thanks
