Q:-5) find the value of i) sin^2 90° + cos^2 90°

$\huge\tt\underline\blue{ANSWER }$

------>>>>Here is your answer<<<<--------

⟹Important formula:-

${sin}^{2} \alpha + {cos \alpha }^{2} = 1$

$⟹ {sin}^{2} 90 + {cos}^{2} 90 = 1$

OR

$⟹ sin90 = 1 \: and \: cos 90 = 0$

$⟹ {sin}^{2} 90 + {cos}^{2} 90 = {(1)}^{2} + {(0)}^{2} = 1$

HOPE IT HELPS YOU..
