Explanation:

### Example Question #21 : Other Differential Functions

Differentiate:

with respect to .

Explanation:

Apply the chain rule: differentiate the "outside" function first. Let .

Differentiate the "inside" function next.

Multiply these two functions to find the derivative of the original function.

### Example Question #22 : How To Find Differential Functions

Evaluate

Explanation:

To integrate the function, integrate each term of the function. e.g., integrate  by increasing the exponent by 1 integer and dividing the term by this new integer: .

Do this for the rest to get .

But remember that every integration requires an arbitrary constant, . Thus, the integral of the function is

### Example Question #211 : Differential Functions

Integrate

Explanation:

We can use trigonometric identities to transform integrals that we typically don't know how to integrate.

Thus,

Integrate

Explanation:

We can use trigonometric identities to integrate functions we typically don't know how to integrate.

Thus,

Evaluate

Explanation:

You can transform the limits of integration via u-substitution.

Let
