With the substitution rule we will be able integrate a wider variety of functions. Not to be copied, used, distributed or revised without explicit written permission from the copyright owner. We will also look at the first part of the Fundamental Theorem of Calculus which shows the very close relationship between derivatives and integrals.
Integration can be used to find areas, volumes, central points and many useful things. But it is easiest to start with finding the area under the curve of a function like this:. So you should really know about Derivatives before reading more! The symbol for "Integral" is a stylish "S" for "Sum", the idea of summing slices :. After the Integral Symbol we put the function we want to find the integral of called the Integrand ,.
It is the "Constant of Integration". It is there because of all the functions whose derivative is 2x :. Because the derivative of a constant is zero. So when we reverse the operation to find the integral we only know 2x , but there could have been a constant of any value. Integrating the flow adding up all the little bits of water gives us the volume of water in the tank.
Derivative: If the tank volume increases by x 2 , then the flow rate must be 2x. You only know the volume is increasing by x 2. We can go in reverse using the derivative, which gives us the slope and find that the flow rate is 2x. If we are lucky enough to find the function on the result side of a derivative, then knowing that derivatives and integrals are opposites we have an answer.
But remember to add C. From the Rules of Derivatives table we see the derivative of sin x is cos x so:. But a lot of this "reversing" has already been done see Rules of Integration. On Rules of Integration there is a "Power Rule" that says:. Learn the Rules of Integration and Practice!
A Definite Integral has actual values to calculate between they are put at the bottom and top of the "S" :. Hide Ads About Ads. Introduction to Integration Integration is a way of adding slices to find the whole. That is a lot of adding up! But we don't have to add them up, as there is a "shortcut". Like here: Example: What is an integral of 2x? We know that the derivative of x 2 is 2x Rules of Integration Calculus Index. And as the slices approach zero in width , the answer approaches the true answer.

It should be noted as well that these applications are presented here, as opposed to Calculus I, simply because many of the integrals that arise from these applications tend to require techniques that we discussed in the previous chapter. Definite integrals can be used to determine the mass of an object if its density function is known. Probability We'll explore their applications in different engineering fields. Extending this idea to the realm of calculus integration, the single integral which uses one variable becomes the double integral which uses two variables. Problem: Do we use calculus in everyday life? Just select your click then download button, and complete an offer to start downloading the ebook.
Solution: (a) Attempts to use integration by parts fail. Expanding (x2 +10)50 to get a The definite integral in Example 1(b) can be evaluated more simply by.
When we integrate to get Inverse Trigonometric Functions back, we have use tricks to get the functions to look like one of the inverse trig forms and then usually use U-Substitution Integration to perform the integral. If you're seeing this message, it means we're having trouble loading external resources on our website. Question 2 True or False.
Note that some sections will have more problems than others and some will have more or less of a variety of problems. Most sections should have a range of difficulty levels in the problems although this will vary from section to section. Here is a list of all the sections for which practice problems have been written as well as a brief description of the material covered in the notes for that particular section.
