1. The problem statement, all variables and given/known data Prove. (sec(x)+1)/(tan(x))=(sin(x))/(1-cos(x)) 2. Relevant equations Trig Identities 3. The attempt at a solution I decided to try and prove the identity by manipulating the function on the right side. I multiplied both the numerator and denominator by (1+cos) and got (sin(x)(1+cos))/(1-cos^2) →(sin(x)(1+cos))/(sin^2) →(1+cos)/(sin) →(csc)+(1/tan) I'm stuck after this point. All help is much appreciated. Thank you.
