Question

sec theta sqrt (1 - sin ^ theta) = 1​

Answer 1

Answer:

sec^2theta.(1-sin^2theta)=1

Step-by-step explanation:

Here, As given in question,

=sec^2theta.(1-sin^2theta)=L.H.S.

=1/cos^2theta.(1-sin^2theta) [sec theta=1/cos theta]

=1/cos^2theta×cos^2 [1-sec^2theta=cos^2theta]

=1=1

LHS=RHS (Proved)
