Question

the value of √1+sin theta. √1- sin theta is

Answer 1

root 1+Sin theta * root 1-sin theta
= root (1+sin theta )(1-sin theta)
= root (1-sin^2 theta)
= root cos^2 theta
= cos theta

Answer 2

hello users....

we have to find the value of
√1+sin θ . √1- sin θ =?

solution:-
using formula:
(a+b)(a-b) = a² - b²
&
1-sin²x = cos²x

here
√1+sin θ . √1- sin θ = √(1²-sin² θ)
= √cos² θ
= cos θ answer
