Question

Help proving a trig identity?

(1-cos x)/(sin x) = (sin x)/(1 + cos x)

Answer 1

taking the right hand side (sinx)/( 1+cosx)
multiply the numerator and denominator by (1-cosx)
sinx/(1-cosx) * (1-cosx) /(1-cosx)

Answer 2

Okay, doing that right now!

Answer 3

Okay so I get sin x (1-cosx) for the numerator & for the denominator 1-cos squared x

Answer 4

you will get sinx(1-cosx) /(1+cosx) (1-cosx)
which will then give sinx (1-cosx) / (1- cos^2x)

Answer 5

Okay now I see how to get the final answer! Thanks so much!
