My teacher always confuses me when she throws T into the mix. i tried replacing with X, didnt help my problem either. i saw in a thread by yovivo, that the help posted could somewhat be applied. so i tried for the first one how the identities might help. kinda went off and got lost again... so im just exhausted with these four problems. thanks for any help..

Directions: Find all values for t in the interval [0,2PI]

1. cot t = csc t

2. sin^2 t - cos^2 t= 1

3.|csct|=2

4. sin^2 t =3/4
