The indefinite integral of , denoted , is defined to be the antiderivative of. In other words, the derivative of is. Since the derivative of a constant is 0, indefinite integrals are defined only up to an arbitrary constant. For example,, since the derivative of is.

Integrate sinx sin3x

The integral of sin 3x is called the anti-derivative of sin 3x as integration is the reverse process differentiation. Sin 3x is an important trigonometric formula that is used to solve various problems in trigonometry. The integral of sin 3x can be calculated using the substitution method and using the sin 3x formula. In this article, we will calculate the integral of sin 3x, prove it using the substitution method and sin 3x formula and determine the definite integral of sin 3x using different limits. The integral of sin 3x can also be evaluated using the substitution method and sin 3x formula. Let us prove this using the substitution method. We will use the following formulas of integration and differentiation:. Using the above formulas, we have. Before proving the integral of sin 3x, we will derive the integral of sin cube x, that is, sin 3 x.
