Question

( 1 + csc x ) ( 1 - sin x ) = cot x cos x

Answer 1

( 1 + csc x ) ( 1 - sin x ) = cot x . cos x
= cot x . cos x
1 - sin x + - 1 = cot x. cos x
- sin x = cot x . cos x
= cot x. cos x
= cot x . cos x
. cos x = cot x . cos 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 ) = . cos x
( 1 + csc x ) ( 1 - sin x ) = . cos x
( 1 + csc x ) ( 1 - sin x ) =
( 1 + csc x ) ( 1 - sin x ) =
( 1 + csc x ) ( 1 - sin x ) = - sin x
( 1 + csc x ) ( 1 - sin x ) = ( 1 + csc x ) ( 1 - sin x )

semoga membantu :) jadikan yang terbaik ya :))
