    1. Do you know how to express $\displaystyle tan\theta$ in terms of sin and cos? What does $\displaystyle csc\theta$ represent? Surely you can do this and do the algebra.

    2. Pick an (x,y) coordinate such that it's situated in quadrant IV, i.e. a positive x with a negative y. A triangle can be created using the values of x and y and then it's a matter of applying the definitions of sin(t), cos(t), and tan(t).
