Question

Sin 60 * cos30 - cos60 * sin30 =sin30

Answer 1

Answer:

$= \sin(60) \cos(30) - \cos(60) \sin(30) \\ = \frac{ \sqrt{3} }{2} \times \frac{ \sqrt{3} }{2} - \frac{1}{2} \times \frac{1}{2} \\ = \frac{3}{4} - \frac{1}{4} \\ = \frac{2}{4} \\ = \frac{1}{2} \\ = \sin(30)$

LHS = RHS

1/2 = 1/2 ( sin 30 = 1/2)
