Help with Trig Identities...i have this problem and i need to proove both sides equal...but u can only touch one side anyways....

(1+sin(x)) cos(x)
------------ + ----------- = 2sec(x)
cos(x) (1+sin(x))

God damm I really do hate math... sorry I cant be anymore help that that.

get them so they have a common denominator, use the sin^2 + cos^2 = 1 thing and go from there.

basically you just have to show that the left hand side is equal to 2/cos.... think of it that way.

Here you go. The only identity I used was cosx^2+sinx^2=1.
