Question

sin² ø- tan² ø+ cos² ø+ sec² ø is equal to?​

Answer 1

Answer:

2

Step-by-step explanation:

We know sin^2 (theta) + cos^2 (theta) = 1 ( eqn 1)

Also 1 + tan^2 (theta) = sec^2 (theta)

hence sec^2 (theta) - tan^2 (theta) = 1 (eqn 2)

Substitute values of eqn 1 and 2, you'll get as

1 + 1 = 2
