enyata [817]

Step-by-step explanation:

$\frac{1}{1 + \sin( \alpha ) } \frac{1}{1 - \sin( \alpha ) } \\ \frac{1 - \sin( \alpha ) + 1 + \sin( \alpha ) }{(1 + \sin( \alpha ))(1 - \sin( \alpha )) } \\ = \frac{2}{1 - {sin}^{2} \alpha } \\ \frac{2}{ {cos}^{2} \alpha } = 2 \: {sec}^{2} \alpha$

Simplify sine squared theta divided by the quantity 1 minus sine squared theta..

timama [110]

Answer: tan^2ø
(i’m gonna use ø as theta because i can’t find it)

explanation:
sin^2ø-1=cos^2ø because of one of the pythagorean identities

sin^2ø/cos^2ø is tan^2ø because sin/cos is tan- opposite/hypotenuse divided by adjacent/hypotenuse is opposite/adjacent

hope that helps- you can comment if you need any more explanation :)
