$\int_{-1}^{2} x\frac{1}{x^2+4}dx$
Learn how to solve problems step by step online. Integrate the function x/(x^2+4) from -1 to 2. Rewrite the fraction \frac{x}{x^2+4} inside the integral as the product of two functions: x\frac{1}{x^2+4}. We can solve the integral \int x\frac{1}{x^2+4}dx by applying integration by parts method to calculate the integral of the product of two functions, using the following formula. First, identify u and calculate du. Now, identify dv and calculate v.
