    intercept

    Find the exact value of the area under the first arch of f(x) = x sin(x). The first arch is between x = 0 and the first positive x-intercept.
    I dont know how i would get the first positive x intercept i know that sine is a wave and the x is going to change the wave by making it bigger but im stuck, please help

    Solve x \sin x = 0.

    Case 1: x = 0.

    Case 2: \sin x = 0.
