Need help you all with this question:(
​

Answer 1

True both each.

Explanation:

Your teacher would probably like you to remember the Trig Identities or allow you to have a cheat sheet for the Quiz or Test.

`(sin(\alpha ))/(sin^(2)(\alpha) +cos2\alpha ) \\\\(sin(\alpha ))/(sin^(2)(\alpha) +[cosx^(2) (\alpha)-sinx^(2) (\alpha )]) \\\\(sin(\alpha ))/(sin^(2)(\alpha) +cosx^(2) (\alpha)-sinx^(2) (\alpha ))\\\\(sin(\alpha ))/([sin^(2)(\alpha) +cosx^(2) (\alpha)]-sinx^(2) (\alpha ))`

`(sin(\alpha ))/(1-sinx^(2) (\alpha ))\\\\(sin(\alpha ))/(cos^(2) (\alpha ))\\\\(sin(\alpha ))/(cos^(2) (\alpha ))\\\\(sin(\alpha ))/(cos(\alpha )*cos(\alpha ))\\\\(sin(\alpha ))/(cos(\alpha ))*(1)/(cos(\alpha )) \\\\tan(\alpha )*sec(\alpha )\\\\(1)/(cot(\alpha ))*sec(\alpha )\\\\(sec(\alpha ))/(cot(\alpha ))`
