WebIntegrals are often described as finding the area under a curve. This description is too narrow: it's like saying multiplication exists to find the area of rectangles. Finding area is a useful application, but not the purpose of multiplication. Key insight: Integrals help us combine numbers when multiplication can't. WebMar 26, 2016 · Given the example, follow these steps: Declare a variable as follows and substitute it into the integral: Let u = sin x. You can substitute this variable into the expression that you want to integrate as follows: Notice that the expression cos x dx still remains and needs to be expressed in terms of u. Differentiate the function u = sin x.

One useful property of indefinite integrals is the constant multiple rule. This rule means that you can pull constants out of the integral, which can simplify the problem. For example, the integral of 2x + 4 is the same as the 2 multiplied by the integral of x + 2. However, it is important that only constants—not variables—are ...
