1. ## Trig help?

I need help with this question:

Find the exact value of tan(v+3pi)
tan v = -3 in the interval (pi/2, pi)

2. edit: removed first part since you no longer ask for it (mine was dodgy anyway), and fixed typos.

Hint: Tan is a periodic function (its value repeats every $\pi$).

if you need a bit more, try calculating
$tan(1)$
$tan(1 + \pi)$
$tan(1 + 2\pi)$
...

wouldn't it still be just tan?
