Formula of 2 sin 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.

This integral can be evaluated using the formula for the integral of sin x. We know that integration is the reverse of the process of differentiation and hence, the integral of 2sinx is also called the antiderivative of 2sinx. In this article, we will compute the integral of 2sinx and derive its formula. We will also evaluate the definite integration of 2sinx with different limits and go through a few solved examples based on a similar concept for a better understanding. Let us now explore the formula for the same in the next section. The image below gives the integral of the 2sinx formula:.

Trigonometry is an amusing and fundamental branch of Mathematics. We study a number of formulas, theorems and equations in trigonometry which has extensive use in science. Using this formula, we can enable ourselves to calculate the sine of the angle whose value is doubled. Sin function is one of the primary trigonometric ratios that is defined as the ratio between the length of the opposite side to that of the length of the hypotenuse in a right-angled triangle. There are many formulas related to sin 2x that can be derived using basic trigonometric formulas. Formulas and identities of sin 2x, cos 2x, tan 2x, cot 2x, sec 2x and cosec 2x are known as double angle formulas because they have angle double of the angle present in their formulas. Sin 2x formula is 2sinxcosx. Before going into the actual proof, first, let us take a look at the formula itself. Observe that the sin2x formula is a product of sinx and cosx. We will start by using the known formula in which sin and cos are multiples of each other.
