Question

sin15°+cos15°=


Pls help me​

Answer 1

Answer:

sin15+cos15

sin (45-30) + cos(45-30)

= (sin45 cos30 - cos45 sin30) + (cos45cos30 + sin45sin30)

$\frac{1}{ \sqrt{2} } ( \frac{ \sqrt{3} }{2} ) - \frac{1}{ \sqrt{2} } ( \frac{1}{2} ) + \frac{1}{ \sqrt{2} } ( \frac{ \sqrt{3} }{2} ) + \frac{1}{ \sqrt{2} } ( \frac{1}{2}) \\ \frac{ \sqrt{3} }{ \sqrt{2} }$

HOPE IT HELPS YOU.......!
