Multplying by a form of 1

  1. Mar 18, 2010 #1
    1. The problem statement, all variables and given/known data

    Integrate 1/(1-secx)dx by multiplying the integrand by a form of 1.


    2. Relevant equations

    any sort of trig identity?

    3. The attempt at a solution

    I've tried multiplying by forms of 1 such as secx+tanx, secx-tanx, and others, but when i do, i just end up with a messy looking integrand.
    any pointers with this and any other problems like it?

    How about multiplying by (1 + sec x)/(1 + sec x)? Is that one you tried?
