    Find the Three Trigonometric Funtions of the Angle by Applying Formulas

    The one I'm having trouble with is, tan \theta \frac{4}{3}, \theta in quadrant III

    I've solved y=\sqrt{3},x=-1, and r=2

    My problem is I can't put \frac {\sqrt 3}{4} in to my calculator. I've tried \frac {1.7321}{2}, but I can't do decimals as fractions.

    I don't understand what you are doing.

    If you are given that \tan(\theta)= \frac{4}{3} then \sin(\theta)= \frac{-4}{5} and \cos(\theta)= \frac{-3}{5}.

    So where are you getting the other values?
    Thanks from Jarod_C
