itz \frac{1}{1+\sec x}

there all sin(x) or cos(x) :-p

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"...

ok ... here's my problem i need to prove that the LHS = RHS sin^2 + 2cos - 1 / 2 + cos - cos^2 = 1 / 1 + sec i tried to use the pythagarean identies and substitute the 1 and 2 but tht isn't getting me anywhere .. please help
