Question

Prove that the left side equals the right side.

(Sinx/1-cosx) + (sinx/1+cosx) = 2 csc x

Answer 1

take LHS,
pull out Sinx,
take LCM
simplify

Answer 2

What is LHS?

Answer 3

Left Hand Side

Answer 4

(Sinx/1-cosx) + (sinx/1+cosx)

Answer 5

pull out Sinx

Answer 6

Ok so I've got sinx(1/cos+1)(1/cos-1).
What do you mean take LCM

Answer 7

\(\large \sin x (\frac{1}{1-\cos x} + \frac{1}{1 + \cos x})\)

Answer 8

OOOHHHH. sec=1/cos Thanks I see it now.

Answer 9

\(\large \sin x (\frac{1}{1-\cos x} + \frac{1}{1 + \cos x})\)

\(\large \sin x (\frac{1+\cos x + 1 - \cos x}{1-\cos^2 x})\)

Answer 10

easy for u :)
