Solving Trigonometric Equations ( a second time)

Revisiting how to solve a trigonometric equation.

Some examples where we get a linear equation to solve:
This won starts with a reciprocal trigonometric function

 This one has been pre-factored for you.
 This one has been pre-factored but it is a double angle. You therefore need to solve for 2theta between 0 radians and 4pi radians.

Some examples where we get a quadratic and then need to factor a quadratic and solve for the angle.

 This one has a trigonometric identity incorporated into it.

The next example has common factoring and a difference of squares.

Finally an example that is quadratic and a double angle question.
