Question

simplify √1- cos^2a / √1- sin^2a.
it's urgent. spams will be Reported. I'll mark Brainliest.​

Answer 1

Answer:

tan(a)

as sin^2(a)= 1- cos^2a

and cos^2a =1- sin^2a.

Answer 2

$\huge \frac{ \sqrt{1 - }{\cos {}^{2}}a }{\sqrt{1 - }{\sin {}^{2}}a}$

$\huge = \frac{( \sqrt{1}) - \cos {}^{2} (a) }{ (\sqrt{1)} - \sin {}^{2} (a) }$

$\huge = \frac{1 - \cos {}^{2}(a) }{1 - \sin {}^{2} (a)}$

$\huge= \frac{ \sin {}^{2}(a) }{1 - \sin {}^{2} (a)}$

$\huge = \frac{ \sin {}^{2}(a) }{\cos {}^{2} (a)}$

$\huge= \tan {}^{2} (a)$
