**Correct answer:**

### Example Question #2 : Finding Definite Integrals

Find

**Possible Answers:**

**Correct answer:**

This is most easily solved by recognizing that .

### Example Question #3 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

Since our , we can't use the power rule. Instead we end up with:

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:

### Example Question #4 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

Since our , we can use the reverse power rule to find the indefinite integral or anti-derivative of our function:

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:

### Example Question #5 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

As it turns out, since our , the power rule really doesn't help us. has a special anti derivative: .

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:

### Example Question #6 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

As it turns out, since our , the power rule really doesn't help us. is the only function that is it's OWN anti-derivative. That means we're still going to be working with .

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:

Because is so small in comparison to the value we got for , our answer will end up being

### Example Question #7 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

Since our , we can use the power rule for all of the terms involved to find our anti-derivative:

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:

### Example Question #8 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

Since our , we can't use the power rule. We have to break up the quotient into separate parts:

.

The integral of 1 should be no problem, but the other half is a bit more tricky:

is really the same as . Since , .

Therefore:

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:

### Example Question #9 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

Since our , we can use the power rule, if we turn it into an exponent:

This means that:

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:

### Example Question #10 : Finding Definite Integrals

**Possible Answers:**

**Correct answer:**

Remember the fundamental theorem of calculus!

Since our , we can't use the power rule, as it has a special antiderivative:

Remember to include the for any anti-derivative or integral taken!

Now we can plug that equation into our FToC equation:

Notice that the c's cancel out. Plug in the given values for a and b and solve:
