$\int_{0}^{4} x\frac{1}{\sqrt{1+2x}}dx$
Learn how to solve definite integrals problems step by step online. Integrate the function x/((1+2x)^1/2) from 0 to 4. Rewrite the fraction \frac{x}{\sqrt{1+2x}} inside the integral as the product of two functions: x\frac{1}{\sqrt{1+2x}}. We can solve the integral \int x\frac{1}{\sqrt{1+2x}}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.
