### 1. Indefinite Integrals as Anti Derivatives

What does an anti-derivative have to do with a derivative? Is a definite integral a self-confident version of an indefinite integral? Learn how to define these in this lesson.

### 2. Antiderivatives of Constants & Power Functions

In the study of calculus, you are frequently called on to find the antiderivative of a function. In this lesson, you'll learn how to find antiderivatives of constants and power functions.

### 3. Antiderivatives of Products of Constants & Functions

Antiderivatives are an undoing of a derivative in a way. This lesson will review what an antiderivative is and will then go on to explain a particular rule that tells us how to find the antiderivative of the product of a constant and a function.

### 4. How to Antidifferentiate Sums

In this lesson, we'll review antiderivatives then explore how to antidifferentiate sums of functions using a formula for the antiderivative of a sum. We'll apply the formula to multiple examples to help solidify our understanding of the concept.

### 5. How to Calculate Integrals of Exponential Functions

Exponential functions are so predictable. It doesn't matter how many times you differentiate e^x, it always stays the same. In this lesson, learn what this means for finding the integrals of such boring functions!

### 6. How to Antidifferentiate Logarithmic Functions

In this lesson, we demonstrate how to evaluate four types of integrals involving a logarithmic function. The method we use for each is Integration by Parts, and one of the key tricks is realizing a constant function is the derivative of a linear function. The natural logarithm works well with this since its derivative is 1/x.

### 7. How to Calculate Integrals of Trigonometric Functions

Ever feel like you are going around in circles? Like, periodically you have your ups and downs? Well, sines and cosines go up and down regularly too. In this lesson, learn how to integrate these circular functions.

### 8. How to Solve Integrals Using Substitution

Some integrals are as easy as riding a bike. But more often, integrals can look like deformed bikes from Mars in the year 3000. In this lesson, you will learn how to transform these scary-looking integrals into simpler ones that really are as easy as riding a bike.

### 9. How to Change Limits of Definite Integrals

In this lesson, we will discuss changing the limits of definite integrals. This is useful when using u-substitution or trigonometric substitution to solve definite integrals and saves time as there is no need to revert back to the original variable.

### 10. Using Integration By Parts

Your mother may have warned you not to bite off more than you can chew. The same thing is true with integration. In this lesson, learn how integration by parts can help you split a big interval into bite-sized pieces!

### 11. Partial Fractions: How to Factorize Fractions with Quadratic Denominators

Adding fractions with different denominators is something you probably learned how to do in algebra. In this lesson, learn how to do the opposite: take a complicated fraction and turn it into two simpler ones.

### 12. How to Integrate Functions With Partial Fractions

In this lesson, learn how to integrate complicated fractions by using the partial fractions technique. That is, you will turn a complicated fraction into something a bit easier to integrate by finding partial fractions!

### 13. Understanding Trigonometric Substitution

Sometimes a simple substitution can make life a lot easier. Imagine how nice it would be if you could replace your federal tax form with a 'Hello, my name is...' name badge! In this lesson, we review how you can use trigonometry to make substitutions to simplify integrals.

### 14. How to Solve Improper Integrals

What does it mean when an integral has limits at infinity? These integrals are 'improper!' In this lesson, learn how to treat infinity as we study the so-called improper integrals.

### 15. Piecewise Integration: Definition & Examples

Integration is finding the area between a function and the x-axis. Piecewise functions have separate expressions based on x-axis conditions. In this lesson, we'll learn how to integrate piecewise functions.
