    The definition of csc(x) = 1/sin(x)
    The definition of sec(x) = 1/cos(x)
    Another great thing to memorize is that tan(x) = sin(x)/cos(x)



    the sin(x) terms will cancel; the cos(x) terms will also cancel so

I have a problem: x/ the square root of (4-x^2) x is = to 2cos theta. I was wondering if I could simplify the denominator to the square too of 4, which is 2, minus the square root of 2cos^2, which is 2cos.
