Example Question #1471 : Calculus Ii

If , what is 

Possible Answers:

Correct answer:

Explanation:

To find the second derivative, first one has to find the first derivative, then take the derivative of this result. 

The derivative of  is .

The derivative of  is , and this is our final answer.

Example Question #1472 : Calculus Ii

What is the second derivative of ?

Possible Answers:

Correct answer:

Explanation:

First, you have to take the first derivative. Multiply the exponent by the coefficient in front of the x term and then also subtract one from the exponent:

Now, take the second derivative from the first derivative, using the same process:

Example Question #345 : Derivative Review

What is the derivative of ?

Possible Answers:

Correct answer:

Explanation:

Recall that when taking the derivative, multiply the exponent by the coefficient in front of the x term and then subtract one from the exponent:

Simplify to get your answer:

Example Question #142 : First And Second Derivatives Of Functions

Example Question #346 : Derivative Review

What is the derivative of ?

Possible Answers:

Correct answer:

Explanation:

To take the derivative, multiply the exponent by the coefficient in front of the x term and then subtract one from the exponent:

Therefore, your answer is:

Example Question #1476 : Calculus Ii

Find the derivative of 

Possible Answers:

Correct answer:

Explanation:

This is a chain rule derivative.  For those problems, we need to start with the outermost derivative and work our way inwards.  The very outermost function is   The derivative of that function is   Here, we simply replace  with   Then, we need to multiply by the derivative of the next chain,   The derivative of that function is  Putting it all together:

In the last step, we take advantage that 

Example Question #351 : Derivatives

Find the derivative of the following function:

.

Possible Answers:

Correct answer:

Explanation:

First, we need to simplify the problem by distributing through the parenthesis.  

Remember, for the second term, if we add exponents when multiplying functions with a common base.

Now, let's take the derivative!  The function  returns itself, and the second term is a chain rule application.

Example Question #351 : Derivative Review

Find the derivative of the following function:

.

Possible Answers:

Correct answer:

Explanation:

For polynomial derivatives, we use the power rule.  We move the exponent to front of the function (and multiply it by the existing coefficient).  Then, we reduce each exponent by one.

Correct answer:

First Derivative 

 

Second Derivative

 

Explanation:

Finding the first derivative: 

Recall the derivative of the natural logarithm function is, 

.                                                            (1)

 

Proceed using equation (1) and the chain rule, 

 

                                                            (2)

 

To find the second derivative, use the quotient rule on equation (2).

 

 

 

 

Example Question #351 : Derivative Review

Determine the second derivative of a function , where the original function is expressed as .

Possible Answers:

None

Correct answer:

Explanation:

Step 1: Find the first derivative of the function:

By using the power rule which states, , the first derivative is,



Step 2: Find the second derivative. To do this, just take the derivative of the former function by using the power rule again.

.

Remember: The derivative of a constant is always zero!!
