Question

What basic trigonometric identity would you use to verify that csc x sec x cot x= csc^2x.

Answer 1

Answer:

See below.

Step-by-step explanation:

I would use cot x =  cos x / sin x:

csc x sec x cot x

= csc x * 1/cos x  * cos x / sin x

The cos x disappears:

= csc x * 1 / sin x

= csc^2 x.
