( 1 + csc x ) ( 1 - sin x ) = cot x . cos x
( 1 + \frac{1}{sin x} ) ( 1 - sin x)
= cot x . cos x
1 - sin x +  \frac{1}{sin x} - 1 = cot x. cos x
 \frac{1}{sin x} - sin x = cot x . cos x
 \frac{1- sin^{2} x }{sin x} = cot x. cos x
 \frac{ cos^{2} x}{sin x} = cot x . cos x
 \frac{cos x}{sin x} . cos x = cot x . cos x
 \frac{1}{tan x} . cos x = cot x . cos x
cot x . cos x = cot x . cos x

atau
( 1 + csc x ) ( 1 - sin x ) = cot x . cos x
( 1 + csc x ) ( 1 - sin x ) =  \frac{1}{tan x} . cos x
( 1 + csc x ) ( 1 - sin x ) =  \frac{cos x}{sin x} . cos x
( 1 + csc x ) ( 1 - sin x ) =  \frac{ cos^{2} x}{sin x}
( 1 + csc x ) ( 1 - sin x ) =  \frac{1- sin^{2} x }{sin x}
( 1 + csc x ) ( 1 - sin x ) =  \frac{1}{sin x} - sin x
( 1 + csc x ) ( 1 - sin x ) = ( 1 + csc x ) ( 1 - sin x )

semoga membantu :) jadikan yang terbaik ya :))
