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

$G(x)=f^{\prime }(x)$ or in other words ${\frac {d}{dx}}$ of $\int \limits _{a(x)}^{b(x)})\ b(x)*f(b(x))-a(x)*f(a(x)dx$

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

= $(0)*f(1)-(-3)*f(1-3x)$ $(3)*f(1-3x)$

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