The area bounded by the parabola $y=x^2$ and the line $y=x$ is

The area bounded by the parabola $y=x^2$ and the line $y=x$ is
  1. $\frac{1}{2}$ sq. units
  2. $\frac{1}{3}$ sq. units
  3. $\frac{2}{3}$ sq. units
  4. $\frac{1}{6}$ sq. units

Solution

The required area is shaded The point of intersection of the curves are $x^2=x \Rightarrow x(x-1)=0$ i.e. $O(0,0)$ and $P(1,1)$ $\begin{aligned} & \therefore A=\int_0^1\left(x-x^2\right) d x \\ & =\left[\frac{x^2}{2}\right]_0^1-\left[\frac{x^3}{3}\right]_0^1=\frac{1}{2}-\frac{1}{3}=\frac{1}{6} \end{aligned}$
