integral sec^-1 x dx

asked by akki
  1. u = arcsec(x)
    x = sec(u)
    dx = secu tanu du

    the integrand now becomes

    u secu tanu du

    Now use integration by parts and it's a cinch.

    If still stuck, just google it and I'm sure you can find lots of detailed solutions.

    The problem is to evaluate the integral 10secxtanx dx, from -1/7 pi to 3/8 pi. What I've done so far is evaluated the integral since secxtanx is a trig identity, so the integral of that is secx. I took out the 10 since it was a
