Question

evaluate (1-sin suare tita) (1+Tan suare tita)​

Answer 1

Answer:

1

Step-by-step explanation:

Given: $(1 - sin^2\alpha )(1 + tan^2\alpha)$

Identities Used: $(1 - sin^2\alpha ) = cos^2\alpha$, $(1 + tan^2\alpha) = sec^2\alpha$

=> $(1 - sin^2\alpha )(1 + tan^2\alpha)$

= $cos^2\alpha *sec^2\alpha$

$= cos^2\alpha *\frac{1}{cos^2\alpha}$

$1$
