A function value is given along with constraints and I must find all other trig functions based on the given values.

Function value: $\displaystyle tan \theta$ is undefined

Constraints: $\displaystyle \pi \le \theta \le 2\pi$

I can't completely figure out the solution but I've done some work "trying".

First..

$\displaystyle tan \theta = \frac{o}{a} = \frac{y}{x}$ meaning that x is equal to 0. because of the constraints I made an unit circle and assumed theta is $\displaystyle \frac{3\pi}{2}$

Therefore,

$\displaystyle sin \theta$ = ?

$\displaystyle cos\theta$ = ?

$\displaystyle tan\theta$ = undefined

$\displaystyle csc\theta$ = ?

$\displaystyle sec\theta$ = undefined

$\displaystyle cot\theta$ = ?

Am I on the right track? Could anyone also point me in the right direction?
