WebSolution: Sine is a trigonometric function of an angle defined as the ratio of the length of the perpendicular (opposite) side to the hypotenuse. A = 30° 2A = 2 × 30° = 60° Thus, sin 2A = sin 60° Substituting the value of sin 60°, sin 60°= √3 / 2 Thus, the value of sin 2A = √3 / 2. What is the value of sin 2A, If A is 30º? Summary: WebAnd that will be the A. Over T. T. Equals two four pi and then we find the terms of our squid which is to our times they are over the T.
