# Calculus 1 : How to find solutions to differential equations

## Example Questions

### Example Question #1311 : Functions

Find of the following equation:

Explanation:

First take the derivative and then solve when x=2.

To find the derivative use the power rule which states when,

the derivative is .

Therefore the derivative of our function is:

### Example Question #261 : Equations

Find  for the following equation:

Undefined

Explanation:

To find the derivative of this function we will need to use the product rule which states to multiply the first function by the derivative of the second function and add that to the product of the second function and the derivative of the first function. In other words,

To do this we will let,

and

and

Now we can find the derivative by plugging in these equations as follows.

Now plug in x=1 and solve.

### Example Question #261 : Equations

Find the solution to the following equation at

Undefined

Explanation:

To solve, we must first find the derivative and then solve when x=-2.

To find the derivative of the function we will use the Power Rule:

Therefore,

Now to solve for -2 we plug it into our x value.

### Example Question #11 : How To Find Solutions To Differential Equations
