comment The Integral of Multiple Tangent Functions
Try increasing the working precision: Integrate[..., WorkingPrecision->100].

So it's down to the method used to compute the derivative. Need to be judicious with tools.

Mathematica is great, but it does have bugs. I've found at least 5 so far in my life time of using it. From infinite summations, to sum convergence conditions, to this !! I've filed another bug report with Mathematica ;-)

comment calculus first impressions
It should be a bit more than just algebraic calculations. Did you not see a limit $\lim$ in the maths somewhere? Do you really understand the limiting process? I'd try some examples and don't jump the gun too soon. Take advantage of the "spare" time you have if you find it easy to understand :-) Or read on further so you will then understand the later lectures!
