Question

(cosecA-sinA)×(secA-cosA)​

Answer 1

Answer:

cosAsinA

Step-by-step explanation:

we have, (cosecA-sinA)(secA-cosA)

(1/sinA-sinA)(1/cosA-cosA)

{(1-sinA²A)/sinA}{(1-cos²A)/cosA}

{cos²A/sinA}{sin²A/cosA}

=> cosAsinA ...ans.

Answer 2

Step-by-step explanation:

$(1 - { \sin(a) }^{2} ) \times (1 - { \cos(a) }^{2} ) \div \sin(a) \times \cos(a) \\ \sin(a) \cos(a)$
