Example Question #31 : Techniques Of Antidifferentiation

Define 

Evaluate .

Possible Answers:

Correct answer:

Explanation:

 has different definitions on  and , so the integral must be rewritten as the sum of two separate integrals:

 

Calculate the integrals separately, then add:

 

 

 


 

 

Example Question #21 : Antiderivatives Following Directly From Derivatives Of Basic Functions

Evaluate the integral

 

Possible Answers:

Correct answer:

Explanation:

To evaluate the integral, we use the rules for integration which tell us

Applying to the integral from the problem statement, we get

Example Question #33 : Techniques Of Antidifferentiation

Integrate:

Possible Answers:

Correct answer:

Explanation:

To evaluate the integral, we can split it into two integrals:

After integrating, we get

where a single constant of integration comes from the sum of the two integration constants from the two individual integrals, added together.

The rules used to integrate are

Example Question #34 : Techniques Of Antidifferentiation

Solve:

Possible Answers:

Correct answer:

Explanation:

The integral is equal to

and was found using the following rule:

where 

Example Question #35 : Techniques Of Antidifferentiation

Solve:

Possible Answers:

Correct answer:

Explanation:

To integrate, we can split the integral into the sum of two separate integrals:

Integrating, we get

which was found using the following rules:

Note that the constants of integration were combined to make a single integration constant in the final answer. 

(The first integral can be rewritten as   for clarity.)
