Question

the value of sin square 60 + cos square 30 is​

Answer 1

Answer:

Sin sq 30= 1/2 x 1/2 = 1/4

Cos sq 60= 1/2 x 1/2= 1/4

1/4 + 1/4 = 2/4= 1/2

Answer 2

$\to \frac{3}{2}$

$\large \bold{ \underline{ \underline{ \: Remember :</p><p> \: \: \: }}}$

$\star \: \sin(60) = \frac{ \sqrt{3} }{2} \\ \\ \star \: \cos(30) = \frac{ \sqrt{3} }{2}$

$\large \bold{ \underline{ \underline{ \: Explaination :</p><p> \: \: \: }}}$

$\to \bold{ \ {sin}^{2} (60) + \ {cos}^{2} (30) } \\ \\ \to {( \: \frac{ \sqrt{3} }{2} \: ) }^{2} + {( \: \frac{ \sqrt{3} }{2} \: ) }^{2} \\ \\ \to \frac{3}{4} + \frac{3}{4} \\ \\ \to \frac{3}{2}$
