WebIt is very common for an elementary function not to have an elementary antiderivative. Proving this is the case for a particular function can be difficult. Your function ex3 happens to be one for which the standard method for showing "impossibility," which dates back in principle to Liouville, works reasonably smoothly. WebDifficult Problems. 1. \int x\left (x^2-3\right)dx x d. We can solve the integral \int x\left (x^2-3\right)dx ∫ x(x2 −3)dx by applying integration by substitution method (also called U-Substitution).

The problem with your current choice of u and d v is that ∫ e − a x 2 d x is not expressible in terms of elementary functions. Fortunately, there is more than one way to break up x 3 e − a x 2 d x into u and d v. Try setting u = x 2 and d v = x e − a x 2 d x. Then, d u = 2 x d x and v = − 1 2 a e − a x 2. punisher mugen char
