and we see that our integrand is in the correct form. The method is called substitution because we substitute part of the integrand with the variable [latex]u[/latex] and part of the integrand with du.It is also referred to as change of variables because we are changing variables to obtain an expression that is easier to work with for applying the integration rules.
SECTION 6.1 Integration by Substitution 391 EXAMPLE 4 Integration by Substitution Find the indefinite integral. SOLUTION Consider the substitution which produces and Substitute for x and dx. Multiply. Power Rule Substitute for u. This form of the antiderivative can be further simplified. You can check this answer by differentiating. 2 15 x 1 3 ...
Section 2.1 Substitution Rule ¶ Subsection 2.1.1 Substitution Rule for Indefinite Integrals. Needless to say, most integration problems we will encounter will not be so simple. That is to say we will require more than the basic integration rules we have seen. Here's a slightly more complicated example: Find
The Substitution Rule for Indefinite Integrals Click here for a printable version of this page. Background. After the last section we now know how to do the following integrals. ... What we’ve done in the work above is called the Substitution Rule. Here is the substitution rule in general. The Substution Rule $$\int f(g(x))g'(x)~dx = \int f(u ...

Example 9. Example 10. Derivative and Integration Rules# Essentially each derivative rule that we have seen, has a complementary integration counterpart.
As stated in many calculus textbooks (and ProofWiki),† the Substitution Rule (for the indefinite integral) is wrong. It is usually stated as: $$\int f \left({g \left({x}\right)}\right) g' \left({x}\right) \ \mathrm d x = \int f \left({u}\right) \ \mathrm d u. \tag{1}$$ But as noted by David Gale in "Teaching Integration by Substitution" (1994 ...
The Substitution Rule. Objectives. Use substitution to evaluate indefinite integrals; Use substitution to evaluate definite integrals; Summary. To find algebraic formulas for antiderivatives of more complicated algebraic functions, we need to think carefully about how we can reverse known differentiation rules. To that end, it is essential that ...
The Substitution Rule for Indefinite Integral: More Examples Click here for a printable version of this page. Introduction. In order to allow these pages to be displayed on the web, we’ve broken the substitution rule examples into two sections. The previous section contains the introduction to the substitution rule and some fairly basic examples.
From the substitution rule for indefinite integrals, if F (x) F (x) is an antiderivative of f (x), f (x), we have. ... All of the properties and rules of integration apply independently, and trigonometric functions may need to be rewritten using a trigonometric identity before we can apply substitution.
THE SUBSTITUTION RULE FOR INDEFINITE INTEGRALS JOHN D. MCCARTHY Abstract. In this note, we explain the meaning of the Substitution Rule for Indefinite Integrals We recall the Substitution Rule for Indefinite Integrals. Theorem 1. If u = g(x) is a differentiable function whose range is an interval I and f is continuous on I, then (1) Z f(g(x ...
In this section we examine a technique, called integration by substitution, to help us find antiderivatives. Specifically, this method helps us find antiderivatives when the integrand is the result of a chain-rule derivative. ... From the substitution rule for indefinite integrals, if [latex]F\left(x\right)[/latex] is an antiderivative of ...

However, only three integration formulas are noted in the rule on integration formulas resulting in inverse trigonometric functions because the remaining three are negative versions of the ones we use. The only difference is whether the integrand is positive or negative. ... Substitution with Indefinite Integrals [latex]\int f\left[g(x)\right ...
The integral on the left-hand side of this equation is usually written in the simpler “differ-ential” form, obtained by treating the dx’s as differentials that cancel. We are thus led to the following rule. L un du, L aun du dx b dx = un+1 n + 1 + C. unsdu>dxd. un+1>sn + 1d 5.5 Indefinite Integrals and the Substitution Rule 369
A definite integral is either a number (when the limits of integration are constants) or a single function (when one or both of the limits of integration are variables). An indefinite integral represents a family of functions, all of which differ by a constant. As you become more familiar with integration, you will get a feel for when to use ...
