    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)

    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)
    ...
