%28sinA%2B1-cosA%29%2F%28cosA-1%2BsinA%29
= %28sinA%2B%281-cosA%29%29%2F%28sinA-%281-cosA%29%29
= (Just like rationalizing the denominator)
=
=2%281%2BsinA-cosA-sinA%2AcosA%29%2F%282%2AcosA-2cos%5E2%28A%29%29 (using sin^2(A)-1 = -cos^2(A))
=2%2A%281%2BsinA%29%2A%281-cosA%29%2F%282%2AcosA%2A%281-cosA%29%29
=%281%2BsinA%29%2FcosA
