The value of (1 + tan2θ)(1 – sinθ)(1 + sinθ) =________.

1.	The value of (1 + tan2θ)(1 – sinθ)(1 + sinθ) =________.
Answer» The value of (1 + tan²θ)(1 – sinθ)(1 + sinθ) = 1. (1 + tan² θ) (1 - tan² θ) = sec² θ x cos² θ = 1

Answer»

The value of (1 + tan²θ)(1 – sinθ)(1 + sinθ) = 1.

(1 + tan² θ) (1 - tan² θ)

= sec² θ x cos² θ

= 1
