Question

Prove that Sec⁴x(1- sin⁴ x) - 2 tan² x =1 (5)​

Answer 1

Answer:

the above solution of the question.

Answer 2

Answer:

tan^2x = -2

Step-by-step explanation:

Sec^4x (1-sin^4x) - 2tan^2x = 5

Sec^4x (cos ^4x) -2tan^2x = 5

1/Cos^4x (cos ^4x) - 2tan^2x = 5

1 - 2tan^2x = 5

-2tan^2x = 5-1

- tan^2x =4/2

tan^2x =- 2
