HELP!!! Simplify cos^2 0 -1/ 4sin^2 0?

Shkiper50 [21]

We need to simpify the given expression. The given expression to us is ,

<u>Given </u><u>Expression</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta }$

<u>Using </u><u>Identity</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies \red{ sin^2\theta + cos^2\theta = 1}$

<u>So </u><u>that</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies - sin^2\theta = cos^2\theta -1$

<u>We </u><u>have</u><u> </u><u>:</u><u>-</u><u> </u>

$\sf\implies \dfrac{ cos^2\theta -1}{4 \ sin^2\theta } \\\\\sf\implies\dfrac{ - sin^2\theta}{4sin^2\theta}=\boxed{\sf -\dfrac{1}{4}}$

<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>-</u><u>1</u><u>/</u><u>4</u><u>. </u>
