    Can someone please explain the steps on how to find the area under the curve from x=0 to x=2.
    When the function y= x/x^2+1.

    \frac{x}{x^2+1} or \frac{x}{x^2}+1?

    Let u=x^2+1

    du=2xdx

    \frac {1}{2}du=xdx

    \frac {1}{2} \int_0^2 \frac {du} {u}

    \frac {1}{2} \bigg [\ln {x^2+1} \bigg ]_0^2
