    exponent in trig functions

    I hate to look stupid, but my trig is a bit rusty... csc2x is the same thing as (csc x)2, correct?

    Yes, \displaystyle \begin{align*} \textrm{trig function}\, ^n{(x)} \end{align*} is shorthand for \displaystyle \begin{align*} \left[ \textrm{trig function}\,(x) \right]^n \end{align*}.
