### Example Question #21 : Finding Indefinite Integrals

What is the indefinite integral of with respect to ?

**Possible Answers:**

**Correct answer:**

To find the indefinite integral, we're going to use the reverse power rule: raise the exponent of the variable by one and then divide by that new exponent.

Be sure to include to compensate for any constant!

### Example Question #21 : Finding Indefinite Integrals

**Possible Answers:**

**Correct answer:**

To find the indefinite integral, or anti-derivative, we can use the reverse power rule. We raise the exponent of each variable by one and divide by that new exponent.

Don't forget to include a to cover any constant!

Simplify.

### Example Question #2241 : High School Math

**Possible Answers:**

**Correct answer:**

To find the indefinite integral of , we can use the reverse power rule. To do this, we raise our exponent by one and then divide the variable by that new exponent.

Don't forget to include a to cover any constant!

Determine the indefinite integral:

**Possible Answers:**

**Correct answer:**

, so this can be rewritten as

Set . Then

and

Substitute:

The outer factor can be absorbed into the constant, and we can substitute back:

### Example Question #62 : Asymptotic And Unbounded Behavior

The integral becomes:

Substitute back:

### Example Question #82 : Calculus Ii — Integrals

**Possible Answers:**

**Correct answer:**

This integral will require a u-substitution.

Let .

Then, differentiating both sides, .

We need to solve for dx in order to replace all x terms with u terms.

.

This is a little tricky because we stilll have x and u terms mixed together. We need to go back to our original substitution.

Now we have an integral that looks more manageable. First, however, we can't forget about the bounds of the definite integral. We were asked to evaluate the integral from to . Because , the bounds will change to and .

Essentially, we have made the following transformation:

.

The latter integral is easier to evaluate.

At this point, we can separate the integral into two smaller integrals.

.

The integral evaluates to -2, so now we just need to worry about the other integral. This will require the use of partial fraction decomposition. We need to rewrite as the sum of two fractions.

We need to solve for the values of A and B.

This means that and . This is a relatively simple system of equations to solve, so I won't go into detail. The end result is that .

Let's now go back to the integral .

Distribute the 2 to both integrals and separate it into two integrals.

.

Remember we need to add this value back to the value of , which we already determined to be -2.

The final answer is .

The term of the Maclaurin series of a function has coefficient

The second derivative of can be found as follows:

The coeficient of in the Maclaurin series is therefore

### Example Question #2243 : High School Math

Give the term of the Taylor series expansion of the function about .

**Possible Answers:**

**Correct answer:**

The term of a Taylor series expansion about is

.

We can find by differentiating twice in succession:

so the term is
