Example Question #1592 : Calculus Ii

Let the initial approximation of a solution of the equation

be .

Use one iteration of Newton's method to find an approximation for . Give your answer to the nearest thousandth.

Possible Answers:

Correct answer:

Explanation:

Rewrite the equation to be solved for  as .

Let 

The problem amounts to finding a zero of . By Newton's method, the second approximation can be derived from the first using the equation

.

Since 

 

and

Use these to find the approximation:

Example Question #469 : Derivative Review

Define .

Give the minimum value of  on the set of all real numbers.

Possible Answers:

The function has no miminum value.

Correct answer:

Explanation:

This function is continuous and differentiable everywhere. First we find the value(s) of  for which .

 

 

Therefore, this is the only possible minimum. We determine whether it is a minimum by evaluating :

Since  has its minimum value at ; it is

.

Example Question #471 : Derivatives

Consider the equation

.

Which of the following is equal to  ?

Possible Answers:

Correct answer:

Explanation:

Example Question #472 : Derivatives

Define .

Give the minimum value of  on the interval  .

Possible Answers:

Correct answer:

Explanation:

We first look for  such that :

The two values on the interval  for which this holds true are , so we evaluate  for the values :

     

     

The minimum value is .

Example Question #473 : Derivative Review

Consider the equation

.

Which of the following is equal to  ?

Possible Answers:

Correct answer:

Explanation:

Example Question #1 : Finding Maximums

Define .

Give the maximum value of  on the interval .

Possible Answers:

Correct answer:

Explanation:

First, we determine if there are any points at which .

 

The only point on the interval on which this is true is .

We test this point as well as the two endpoints,  and , by evaluating  for each of these values.

 

Therefore,  assumes its maximum on this interval at the point , and .

Example Question #473 : Derivatives
