Nettet9. apr. 2024 · Step 1/2 First, let's make a substitution to simplify the integrand. Let u = tan(x), so du = sec^2(x) dx. Also, note that as x goes from 0 to infinity, u goes from 0 to infinity as well. Nettet73. To build on kee wen's answer and provide more readability, here is an analytic method of obtaining a definite integral for the Gaussian function over the entire real line: Let I = ∫ − ∞ ∞ e − x 2 d x. Then, I 2 = ( ∫ − ∞ ∞ e − x 2 d x) × ( ∫ − ∞ ∞ e − y 2 d y) = ∫ …

My physics professor today wrote on the blackboard: ∫∞ ∞f(x)dx = 0 for every function f. And the proof he gave was: ∫∞ ∞f(x)dx = …
NettetCase 2: you don’t know how to compute the integral In this case you can’t even get to the point of having a difficult limit to evaluate. So probably you can’t evaluate the improper integral. But you can and should still try to answer whether the integral has a finite value versus being undefined. This is where the comparison tests come in. NettetIntegrate the function xe^(-x^2) from 0 to \infty. We can solve the integral \int_{0}^{\infty } xe^{-x^2}dx by applying integration by substitution method (also called U-Substitution). …
