## Cálculo integral | Khan Academy

The first half of this chapter is devoted to indefinite integrals and the last half is devoted to definite integrals. Here is a integrales por sustitucion listing of the material that is in this chapter.

Indefinite Integrals — In this section we will start off the chapter with the definition and integrales por sustitucion of indefinite integrals.

We will not be computing many indefinite integrals in this section.

This section is devoted to simply defining what an indefinite integral integrales por sustitucion and to give many of the properties of the indefinite integral.

Actually computing indefinite integrals will start in the next section. Computing Indefinite Integrals — In this section we will compute some indefinite integrals. The integrals in this section will tend to be those that do not require a lot of manipulation of the integrales por sustitucion we are integrating in order to actually compute the integral.

As we will see starting in the next section many integrals do require some manipulation of the function before we can actually do the integral.

We will also take a quick look at an application of indefinite integrals. Substitution Rule for Indefinite Integrals — In this section we will start using one of the integrales por sustitucion common and useful integration techniques — Integrales por sustitucion Substitution Rule.

With the substitution rule we will be able integrate a wider variety of functions. The integrals in this section will all require some manipulation of the function integrales por sustitucion to integrating unlike most of the integrals from the previous section where all we really needed were the basic integration formulas.

More Substitution Rule — In this section we will continue to look at the substitution rule. The problems in this section will tend to be a little more involved than those in the previous section.

### Tangent half-angle substitution

Variable changes I will begin by indicating what are the changes of variable to be made depending on the radical and the terms integrales por sustitucion have inside.

These variable changes are called trigonometric substitutions because trigonometric ratios are used in expressions.

We have integrales por sustitucion cases: First case of trigonometric substitution When in the function to be integrated the square root of a number squared minus a variable x squared appears, i. The trigonometric substitution to integrales por sustitucion done in this case is to equal the variable x to the number multiplied by the sine of t: Second case of trigonometric substitution When in the function to be integrated the square root of a number squared plus a variable x squared appears, that is, in this way: In this case, the trigonometric substitution to be made is to equal the variable x to the number multiplied by the tangent of t: Third case of trigonometric substitution The third case of trigonometric substitution is when the square root of variable x squared minus a number squared appears in the function to be integrated: The trigonometric substitution to be performed is to equal x to the number divided by the sine of t: There are other ways to solve irrational integrals.

Resolved exercise of an irrational integral by means of trigonometric substitution We are going to solve an example of an irrational integral in which we have to make some of the variable changes proposed in the previous section.

We have the following integral: This is the integral of an irrational function, since we have a radical, but we do not have to know what the method of resolution or the change of variable to be carried out is.

Other possibilities have to be ruled out first. If the integral had been this way:
