Integral of x 1 1 2

We have so far integrated "over'' intervals, areas, and volumes with single, double, and triple integrals. We now investigate integration over or "along'' a curve—"line integrals'' are really "curve integrals''.

The power rule of integration is one of the rules of integration and that is used to find the integral in terms of a variable, say x of powers of x. To apply the power rule of integration, the exponent of x can be any number positive, 0, or negative just other than Let us learn how to derive and apply the power rule of integration along with many more examples. The power rule of integration is used to integrate the functions with exponents. To apply this rule, we simply add "1" to the exponent and we divide the result by the same exponent of the result.

One difficult part of computing double integrals is determining the limits of integration, i. Changing the order of integration is slightly tricky because its hard to write down a specific algorithm for the procedure. We demonstrate this process with examples. The simplest region other than a rectangle for reversing the integration order is a triangle. You can see how to change the order of integration for a triangle by comparing example 2 with example 2' on the page of double integral examples. In this page, we give some further examples changing the integration order. We have also labeled all the corners of the region. This latter pair of inequalites determine the bounds for integral. Sometimes you need to change the order of integration to get a tractable integral. Here's an example that's a bit more tricky. Reverse the order of integration in the following integral. Looking closely at the picture, we see this cannot be the case. If you'd like more double integral examples, you can study some introductory double integral examples. You can also take a look at double integral examples from the special cases of interpreting double integrals as area and double integrals as volume.

For good measure, here is one more example. Trigonometric Substitutions 4. Power Rule of Integration Derivation 3.

We begin with an example where blindly applying the Fundamental Theorem of Calculus can give an incorrect result. Formalizing this example leads to the concept of an improper integral. There are two ways to extend the Fundamental Theorem of Calculus. One is to use an infinite interval , i. One of the most important applications of this concept is probability distributions because determining quantities like the cumulative distribution or expected value typically require integrals on infinite intervals.

You can also take a look at double integral examples from the special cases of interpreting double integrals as area and double integrals as volume. Lagrange Multipliers 15 Multiple Integration 1. Taylor's Theorem Evaluate it if it is convergent. Recall that in the simplest case, the work done by a force on an object is equal to the magnitude of the force times the distance the object moves; this assumes that the force is constant and in the direction of motion. Approximating the area under a curve. Home » Vector Calculus » Line Integrals. But this rule is used to find the integrals of non-zero constants and the integral of zero as well. Since we are dealing with limits, we are interested in convergence and divergence of the improper integral. The Divergence Theorem 17 Differential Equations 1. The Fundamental Theorem of Line Integrals 4. Additional exercises 9 Applications of Integration 1. The second derivative test 4.

Alternating Series 5. We first solve the corresponding indefinite integral using the following substitution:. Maths Questions. Volume 4. Otherwise, we say the improper integral diverges. Substitution 2. We have already dealt with examples in which the force is not constant; now we are prepared to examine what happens when the force is not parallel to the direction of motion.
