Question

which value of theta is tan theta equal to sin theta?
pi, pi/2,  pi/4 or pi/6

anonymous · Answer

Since $$
\tan\theta = \frac{\sin\theta}{\cos\theta}
$$You want $\cos\theta=1$

anonymous · Answer

still not sure how to go about getting an answer even with that equation

anonymous · Answer

You should know what $cos\theta$ is equal to at those given angles.  If you don't, then you must learn them.

not sure what to do with the equation

anonymous · Answer

what given angles

anonymous · Answer

$$
\pi, \pi/2,  \pi/4 \text{ or } \pi/6
$$

ok

anonymous · Answer

this is something that I just must memorize?

Yes, I would definitely recommend memorizing them... I can derive them for you, but it is not fun.
