Sin 2x cos x

Sin 2x formula is one of the double angle formulas in trigonometry. Using this formula, we can find the sine of the angle whose value is doubled. We are familiar that sin is one of the primary trigonometric ratios that is defined as the ratio of the length of the opposite side of the angle to that of the length of the hypotenuse in a right-angled triangle. There are various sin 2x formulas and can be verified by using basic trigonometric formulas. Sin 2x is a trigonometric formula in trigonometry that is used to solve various trigonometric, integration, and differentiation problems. It is used to simplify the various trigonometric expressions. Sin 2x formula can be expressed in different forms using different formulas in trigonometry. The domain of sin 2x is the set of all real numbers. As the range of sine function is [-1, 1], the range of sin 2x is also [-1, 1].
