Question

4 tan^2 A - 4 sec^2 A​

Answer 1

Step-by-step explanation:

4 tan^2 A - 4 sec^2 A

= 4 ( tan^2 A - sec^2 A )

= 4 × -1

= -4

Answer 2

Answer:

4 tan^2 A - 4 sec^2 A = - 4

Step-by-step explanation:

= 4 tan^2 A - 4 sec^2 A

= 4(tan^2 A - 4 sec^2 A)

= 4(-1) [since, tan^2 A + 1 = sec^2 A]

=> - 4

$\boxed{\Large{\purple{\mathsf{\therefore 4\:tan^2 A - 4\: sec^2 A = - 4}}}}$
