WebCalculus. Evaluate the Integral integral of 3xe^ (-x) with respect to x. ∫ 3xe−xdx ∫ 3 x e - x d x. Since 3 3 is constant with respect to x x, move 3 3 out of the integral. 3∫ xe−xdx 3 ∫ x e - x d x. Integrate by parts using the formula ∫ udv = uv−∫ vdu ∫ u d v = u v - ∫ v d u, where u = x u = x and dv = e−x d v = e - x. WebIntegral of Trigonometric Function: If an angle of a sine function is represented by a quadratic function and the derivative of this quadratic function is present in the integrand, then substitute an arbitrary variable u for the quadratic function and apply the common formulas. {eq}\begin{align*} \displaystyle \frac{\mathrm{d} (x^a)}{\mathrm{d} x}&=ax^{a …
