Hello In every physics book they explain how to compute the force that a spring exert if one of its ends is fixed to a wall (or equivalent) and the other end is compressed or stretched. But how to deal with the problem if both ends are 'free'. For example, suppose you have two blocks...

Thank you, Calculus with Complex Numbers, by Reade, is what I was needing!

Kreyszig's seems good for reference, but not for learning the topics.

Is there a gentle textbook of complex analysis? Something equivalent to Larson's Calculus (or Stewart's). I have Schaum's Outline of Complex Variables (Spiegel-Lipschutz), and it's not bad.

Hi, I'm trying to find the series representation of f(x)=\int_{0}^{x} \frac{e^{t}}{1+t}dt . I have found it ussing the Maclaurin series, differenciating multiple times and finding a pattern. But I think it must be an eassier way, using the power series of elementary functions. I know that...

Hi, I don't understand why in some texts they put that infinitesimal volume dV = dx dy dz. If V = x y z, infinitesimal volume should be dV = y z dx + x z dy + x y dz, by partial differentiation. Thanks
