SUMMARY
The integral of the function 2t^2/(1+t^2)^2 can be effectively solved using integration by parts, specifically with the formula ∫u'vdt = uv - ∫uv'dt. The recommended choice for u' is 2t/(1+t^2)^2 and for v, t. A common mistake in the discussion was the incorrect application of the derivative, leading to confusion in the solution process.
