i need some read up material regarding the title any links or references please?

tomorrows match against south africa will be an awesome one

A plane

We know that arctan x is differentiable u = arctan x du/dx = 1/1+x^2 x^2dx = dv so v = x^3/3 now int udv = uv - int vdu/dx dx = x^3(arctan x) - int (x^3/3(1+x^2) dx) let 1+ x^ 2 = t x^2 = (t-1) 2xdx = - dt so we get x^3/1(1+x^2) dx = x^2xdx/(1+x^2)/3 now you can proceed as = (t-1) (-dt/6)/t...
