    Proving sin^2 + 2cos - 1 / 2 + cos - cos^2 = 1 / 1 + sec

    ummm ok .. here's what i got sin^2 + 2cos - 1 / 2 + cos - cos^2 = 1 / 1 + sec LHS : = sin^2 + cos + cos - sin^2 - cos^2 / 1 + sin^2 + cos^2 + cos - cos^2 ... here i canceled the "sin^2" and " - sin^2" on the top and in the bottom i canceled the "cos^2" and " - cos^2"...
