(secA - cosecA) (1+tanA+cotA) = tanAsecA - cotAcosecA

Answer 1

Answer:

refer to the attachment for the solution.

$..$

Step-by-step explanation:

formula used :

$\frac{sin \alpha }{cosa \alpha } = tan\alpha \\ \\ \frac{cos \alpha }{sin \alpha } = cot \alpha \\ \\ \sec( \alpha ) = \frac{1}{ \cos( \alpha ) }$
