Integral(-3*x, (x, 0, 1))
Detail solution
  1. The integral of a constant times a function is the constant times the integral of the function:

    (3x)dx=3xdx\int \left(- 3 x\right)\, dx = - 3 \int x\, dx

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

      xdx=x22\int x\, dx = \frac{x^{2}}{2}

    So, the result is: 3x22- \frac{3 x^{2}}{2}

  2. Add the constant of integration:

    3x22+constant- \frac{3 x^{2}}{2}+ \mathrm{constant}


The answer is:

3x22+constant- \frac{3 x^{2}}{2}+ \mathrm{constant}
