Several questions from my homework, any are appreciated. Thanks!

Solve:

1) sinx-tanx=0

2) 3csc^2x=4

Find all solutions within (0,2pi)

3) cos4x(cosx-1)=0

4) cos4x-7cos2x=8

Use inverse functions where necessary to find solutions from 0 to 2pi

5) sin^2x-2sinx=0

Find the exact value of the tangent of the angle

6) (25pi)/12=(11pi)/6+(pi/4)
