What is the value of sin 2A, If A is 30º?
Sine is a trigonometric function of an angle defined as the ratio of the length of the perpendicular(opposite) side to the hypotenuse.
Answer: The value of sin 2A is √ 3 / 2
Let's look at the solution.
A = 30°
2A = 2 × 30° = 60°
Thus, sin 2A = sin 60°
Substituting the value of sin 60°,
sin 60°= √ 3 / 2
