WebFeb 2, 2015 · $\begingroup$ Thanks for the really quick reply, I should've clarified more where my mental block really is. I thought about completing the square but I end up getting the integral (using your notation of u =(x+.5)) $$\int\frac{u+\frac{3}{4}}{u^2 +\frac{3}{4}}du$$ which I know must relate to arctan somehow since $\int\frac{1}{x^2 +1} = arctan(x) +c$ … Web$$ ^1/^2 ∫0 x^3 arctan x dx $$ (four decimal places). ...
