    CSC, Sec, Cot, and CSC^-1, Sec^-1, Cot^-1 on Calc

    How would I imput all of these into a TI 83/84 where there are no buttons to imput them help would be of essence...

    csc(x) = \frac{1}{sin(x)}

    sec(x) = \frac{1}{cos(x)}

    cot(x) = \frac{1}{tan(x)}

    So for csc \left ( \frac{ \pi}{3} \right ), for example, find sin \left ( \frac{ \pi}{3} \right ) = \frac{\sqrt{3}}{2} and take the inverse (the x^{-1} button): csc \left ( \frac{ \pi}{3} \right ) = \frac{2}{\sqrt{3}} = \frac{2\sqrt{3}}{3}.

    For the inverses the process is similar. For example: sec^{-1}(2) , you would find cos^{-1} \left ( \frac{1}{2} \right ) = \frac{\pi}{3}.
