comment Transform derivative term of 2nd order
Yes, this question probably should be migrated to Math.SE (if they want it).

@Must: I don't know yet. Let me consult with the math mods.

comment Contiguous prime numbers with MPI (Want more ideas for an efficient algorithm)
scicomp.SE would also gladly take your question; we take lots of questions on MPI, and on the practical implementation of parallel algorithms. (I'm a mod on scicomp.SE.)

comment Rapid approximation of $\tanh(x)$
I thought about that algorithm, too, until I saw the "no table lookup" part.

comment Matrix-Square Root
I thought about the polar decomposition method, too, when I looked at the problem, but then I thought about calculating it, looked it up, and came to a similar conclusion as J.M..

comment Applied ODEs in trajectory problem
Just to clarify, does $v$ have constant magnitude in the problem statement, or does $u + v$ have constant magnitude? If $u + v$ has constant magnitude, then I would expect both the magnitude and direction of $v$ to vary with the position of the boat, because $u$ is a constant vector.

comment Find roots of sum of sinusoids
Just out of curiosity: if this equation describes the motion of a point and a line, is there any way that you could set it up differently, as a system of ODEs, where the collision event is described by the root of an equation? There are event detection algorithms for numerical integrators that work well in such circumstances.
