SOLUTION: Prove the following trigonometric identity: (sin(x))/(1-cos(x)) + (1-cos(x))/(sin(x)) = 2csc(x)

Question 860032: Prove the following trigonometric identity:
(sin(x))/(1-cos(x)) + (1-cos(x))/(sin(x)) = 2csc(x)

LHS

LCM of denominator
(1-cos(x)(sin(x))
we get /

(sin^2(x)+1-2cos(x)+cos^2(x))/((1-cos(x)*sin(x))

(2-2cos(x))/((1-cos(x)*sin(x))
2(1-cos(x))/(1-cos(x)*sin(x))
=2/sin(x)
=2csc (x)
= RHS
