$G(x)=f^{\prime }(x)$ or in other words ${\frac {d}{dx}}$ of $\int \limits _{a(x)}^{b(x)}F(x)dx$ is Failed to parse (Conversion error. Server ("https://en.wikipedia.org/api/rest_") reported: "Cannot get mml. Server problem."): {\displaystyle \ b(x)*f(b(x))-a(x)*f(a(x))}

$y=\int \limits _{1-3x}^{1}{\frac {x^{3}}{(1+u^{2})}}dx$

so $y=\int \limits _{1-3x}^{1}{\frac {1}{(1+u^{2})}}x^{3},dx$

using the formula we get y=$(0)*f(1)-(-3)*f(1-3x)$ $(3)*f(1-3x)$

which is=$3*(1-3x)^{3}*{\frac {1}{(1+(1-3x)^{2})}}$

or simplified to ${\frac {3*(1-3x)^{3}}{(1+(1-3x)^{2})}}$
