1. Solve each equation for the domain interval 0 less than or equal to x less than or equal to 2pie. Round the answers to the nearest hundredth of a radian, if necessary.
2. Simplify each trigonometric expression.
a) sinx (Supposed to be sinx divided by tanxcosx)
b) sin4x+sinsquaredxcossquaredx (sin to the 4)
3. Prove each identity.
a) tanx+ 1 = 1
