Answer:

I really think u wrote the wrong question.

DISCLAIMER READ IT FULL

Step-by-step explanation:

Because in any way it doesn't give the answer.

let me explain.

cot∅ × tan∅ = 1

and in RHS take (2cos^2∅-1)/sin∅.cos∅

see the possibilities

in 2cos^2∅-1/sin∅.cos∅

putting cos^2 = 1-sin^2∅ we get

2(1-sin^2∅)-1/sin∅.cos∅

= 2-2sin^2∅-1/sin∅.cos∅

= 1-2sin^2∅/sin∅.cos∅

which at the end doesn't give 1

taking another possibility in (2cos^2∅-1)/sin∅.cos∅

2cos^2∅-1/sin∅.cos∅

= 2cos^2∅-(sin^2∅ + cos^2∅)/ sin∅.cos∅

= 2cos^2∅-sin^2∅-cos^2∅/ sin∅.cos∅

= cos^2-sin^2∅ /sin∅.cos∅

= (cos∅+sin∅)(cos∅-sin∅) /sin∅.cos∅

which after solving doesn't give 1

SO I REALLY THINK YOU TYPED WRONG QUESTION
