    Here are some nice ones (nothing too tricky about them):

    Prove that \tan (3x) = \dfrac{3 \tan x -\tan^3 x}{1-3 \tan^2 x}

    and

    Given that \sin x \cos y + 3 \cos x \sin y = 2 \sin x \sin y - 4 \cos x \cos y , express tan y in terms of tan x.
    The second one is nice. The first one is just a rather tedious process though, imo

    \tan (A\pm B) = \dfrac{\tan A \pm \tan B}{1 \mp \tan A \tan B}

    Yeah, the first one is very tedious

    Didn't bother with the first one

    I got \tan y = \displaystyle\frac{\tan x +4}{2\tan x - 3} for the second one

    :lol: econometrics would be good for you..

    I was in Business Studies... And for a break even chart... I was like:

    Break Even Point = E

     \displaystyle\int_{a}^{b} f(x) - \displaystyle\int_{a}^{b} g(x) = Profit where a > E .

    If a < E, | \displaystyle\int_{a}^{b} f(x) - \displaystyle\int_{a}^{b} g(x) | = Loss

    Lol, my bad badly worded. It doesn't matter anyway, doubt you would be able to in case you are secretly working for a big accounting firm! :ninja:
