In these lessons, we introduce a notation for antiderivatives called the Indefinite Integral. We will also give a list of integration formulas that would be useful to know.

The notation is used for an antiderivative of *f* and is called the **indefinite integral**.

The following is a table of formulas of the commonly used Indefinite Integrals. You can verify any of the formulas by differentiating the function on the right side and obtaining the integrand.

** Example: **

Find the general indefinite integral

** Solution: **

The connection between the definite integral and indefinite integral is given by the second part of the Fundamental Theorem of Calculus.

If *f* is continuous on [*a*, *b*] then

Take note that a definite integral is a number, whereas an indefinite integral is a function.

**Example: **

Evaluate

** Solution: **

An indefinite integral is a function that takes the antiderivative of another function. It is visually represented as an integral symbol, a function, and then a dx at the end. The indefinite integral is an easier way to symbolize taking the antiderivative. The indefinite integral is related to the definite integral, but the two are not the same.

Antiderivatives and indefinite integrals.

Indefinite integrals are functions that do the opposite of what derivatives do. They represent taking the antiderivatives of functions. A formula useful for solving indefinite integrals is that the integral of x to the nth power is one divided by n+1 times x to the n+1 power, all plus a constant term.

Not all indefinite integrals follow one simple rule. Some are slightly more complicated, but they can be made easier by remembering the derivatives they came from. These complicated indefinite integrals include the integral of a constant (the constant times x), the integral of e

Basic Indefinite Integration (Polynomial, Exponential, Quotient)

This video provides three basic examples of how to determine antiderivatives using integration formulas.

Here are some basic integration formulas you should know.

This video shows how to set up a definite integral using Riemann Sums. The Riemann Sums will be computed in Part 2.
