Re: Step by step answer ?
If you want to see how derivatives are calculated step-by-step, go to calc101.com. To see how indefinite integrals are calculated step-by-step, go to calc101.com but you have to pay a modest fee in this case (except for some "canned" examples). However, the procedures shown at that site, especially for integrals do not have to be using -- and probably do NOT use -- the actual algorithm that the Mathematica kernel uses! For example, an efficient way to evaluate many integrals of rational functions is to write down the form of the integral (involving perhaps inverse trig functions, logs, etc.) with as-yet-unknown coefficients, then to differentiate the form of the result, equate it with the given function to be integrated, and solve algebraic equations for the unknown coefficients. On the other hand, this is NOT the way that integration of rational functions is normally taught in calculus!
