Integral $intlimits^{infty}_0frac{tan^{-1}t }{(1+t)^{n+1}} dt$

I'm having a good amount of trouble evaluating this: $$intlimits^{infty}_0frac{tan^{-1}(t)dt}{(1+t)^{n+1}}, n>0$$Here are some methods I've tried:$$intlimits^{infty}_0frac{tan^{-1}(t)dt}{(1+t)^{n+1}}=frac1nintlimits^{infty}_0frac{dt}{(1+t^2)(1+t)^{n}}$$using integration by parts. I then tried more integration by...

$$frac1{x} = 4$$If multiplied by $x$ both sides,$$1 = 4x$$Then it looks like linear equation in one variable. But is such multiplication by variable...
