Question

find the value of (1+cotA + cosec A )( 1+ tan A - sec A).​

Answer 1

Answer:

Answer is 2.

Step-by-step explanation:

Refer to the picture above for solution.

The identities I used for solving are as follows:

sin^2 A + cos^2 A =1.

cotA=(cosA/sinA)

cosecA=(1/sinA)

tanA=(sinA/cosA)

secA=(1/cosA)
