comment projecting a RegionProduct into 3D space
In this context of regions in Euclidean space, this operation is more commonly known as the Minkowski sum. There doesn't appear to be a built-in method for it. If TransformedRegion accepted two regions as input, you could have done TransformedRegion[r1, r2, Function[{p1, p2}, p1 + p2]], but that doesn't work right now.

Have you looked at BandpassFilter?

comment Need help with GRE study question
This question appears to be off-topic because it is not about the Mathematica computer algebra software.

comment Manahalobis distance between two vectors
That's not what the Mahalanobis distance is. The covariance matrix should be a third parameter independent of u and v.

comment How to generate random points in a region?
Ah, I should have known my randomBarycentric function was (the special case of) a well-known probability distribution.

comment Curve fit based on minimal data
Consider the first example under Notes. If you just knew the positions of the two points and their associated tangents, how would you know how large to make the circle?

In this case just replacing NMaximize and NMinimize with Maximize and Minimize works.

comment Is there a way to logically test an optional color input inside a module?
I guess you want a pattern that matches colors.

comment Joining ordered set of points with splines in spiral
@ybeltukov: Ah, there is that. But under "Possible Issues" it says that the interpolating function may not be differentiable, without mentioning that the spline method does not have this issue.

comment Joining ordered set of points with splines in spiral
It turns out that nondifferentiability is only a problem if you don't use the "Spline" method. I wonder why the documentation doesn't mention this.
