How do you solve #\sin^2 x - 2 \sin x - 3 = 0# over the interval #[0,2pi] How to integrate sin^2 x using the addition formula for cos(2x) and a trigonometric identity. As many people have pointed out by now, sin2x is simply a "nickname" for (sinx)2. Therefore, sin2 30 = (sin30)2 = (1 / 2)2 = 1 / 4. As it happens, though, there is another useful thing we can say about sin2x: sin2x = (sinx)2 = 1 2(1 − cos(2x)). Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals.

Sin 2x Cos 2x is one such trigonometric identity that is important to solve a variety of trigonometry questions. (image will be uploaded soon) Sine (sin): Sine function of an angle (theta) is the ratio of the opposite side to the hypotenuse. In other words, sinθ is the opposite side divided by the hypotenuse.
