### Example Question #537 : Integrals

Explanation:

Step 1: Integrate:

Step 2: Evaluate at the upper limit:

Plug in .

Step 3: Evaluate at the lower limit:

Plug in .

Step 4: Take the valuation at the lower limit and subtract it FROM the upper limit:

The integration of  is

### Example Question #538 : Integrals

Evaluate:

Explanation:

Step 1: Take the antiderivative of each term:

Step 2: Put all the antiderivatives in step 1 together based on the signs in the integral...

Step 3: Plug in the upper and lower limits:

Upper Limit is , lower limit is .

Plug in :

Plug in . Since all terms have , the value will be

Step 4: Subtract the value of the lower limit from the upper limit:

The value of this integral is .

### Example Question #539 : Integrals

Explanation:

First, integrate this expression. Remember to raise the exponent by 1 and then also put that result on the denominator:

Now, evaluate at 2 and then 0. Subtract the results:

### Example Question #540 : Integrals

Explanation:

First, take the 4 outside of the integral sign and rewrite the radical as a fractional exponent. It's easier to visualize that when integrating:

Now integrate. Remember to raise the exponent by 1 and also put that result on the denominator:

Simplify and multiply by the 4 that you took out:

Now evaluate at 2 and then 0. Subtract the results:
