    Integration

    I am doing integration and I just want to see if these are right before I continue to the next step:
    intergrator
    x^(-0.3)dx=1.42857x^0.7
    (1/x^2 -1/x^3)dx=1-2x/2x^2
    (x^(1/3)-3x^(-2/3)+6)dx=3/4∛x(x+8x^(2/3)+3)


    Thanks!

    use \int x^{n} dx = \frac{x^{n+1}}{n+1}+c

    therefore

    \int \frac{1}{x^2}- \frac{1}{x^2} dx = \int x^{-2}- x^{-3} dx = \frac{x^{-1}}{-1}-\frac{x^{-2}}{-2}+c
