014x21dx\int\limits_{0}^{1} 4 x^{2} \cdot 1\, dx
Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    4x21dx=4x2dx\int 4 x^{2} \cdot 1\, dx = 4 \int x^{2}\, dx

    1. The integral of xnx^{n} is xn+1n+1\frac{x^{n + 1}}{n + 1} when n1n \neq -1:

      x2dx=x33\int x^{2}\, dx = \frac{x^{3}}{3}

    So, the result is: 4x33\frac{4 x^{3}}{3}

  2. Add the constant of integration:

    4x33+constant\frac{4 x^{3}}{3}+ \mathrm{constant}


The answer is:

4x33+constant\frac{4 x^{3}}{3}+ \mathrm{constant}
