Question
\[ \int dx_1dx_2...dx_d e^{(x^2_1+x^2_2+...+x^2_d)^{r/2}} = \frac{\pi ^{d/2}(d/r)!}{(d/2)!} \]
How can I derive this answer?
The method of integration to use depends on the type of function you are trying to integrate. Some common methods include substitution, integration by parts, and partial fractions. It is important to understand the properties and rules of each method in order to determine which one is most suitable for your problem. Practice and experience can also help in selecting the appropriate method.
Yes, there are calculators that can solve integrals, but they may not always be accurate or provide a step-by-step solution. It is important to have a good understanding of integration techniques in order to verify the results from a calculator.
A definite integral has specific limits of integration and gives a numerical value as the result. It represents the area under the curve of a function between those limits. An indefinite integral has no limits and gives a general formula for the antiderivative of a function.
One way to check if your integration is correct is to take the derivative of the result and see if it matches the original function. You can also use online integration calculators or ask a friend or colleague to check your work.
Yes, integration has many real-world applications, such as calculating the area under a curve, finding the volume of a solid, or determining the displacement of an object. It is a powerful tool in mathematics and is used in various fields, including physics, engineering, and economics.
