Question

Cos A = √3\2 Find Sin2 A​

Answer 1

Answer:

$\frac{\sqrt{3} }{2}$

Step-by-step explanation:

$Cos A= \frac{\sqrt{3} }{2} \\\\Cos^{2} A + Sin^{2} A = 1\\(\frac{ \sqrt{3}}{2} )^{2} + Sin^{2} A = 1\\\\Sin^{2} A = \frac{1}{4}\\\\Sin A = \frac{1}{2} \\\\Sin 2A = 2SinA CosA\\ = 2 * \frac{1}{2} * \frac{\sqrt{3} }{2} \\\\ = \frac{\sqrt{3} }{2}$
