Question

find the value of (cosec^A-1)tan^A
​

Answer 1

Answer:

A)If your question is (cosec^2A-1)tan^2A

Then answer is 1

B)If your question is (cosecA-1)tanA

Then answer is (1-sinA)/cosA

Step-by-step explanation:

A)Using identity

$cot {}^{2} a + 1 = cosec {}^{2} a$

cosec^2A-1=cot^2A

Now

cot^2A= 1/tan^2A

1/tan^2A*tan^2A = 1

B)(cosecA-1)tanA=cosecAtanA-tanA

=1/sinA*sinA/cosA-sinA/cosA

=(1-sinA)/cosA
