comment quick question on an example of the derivative as a linear map.
Nice answer. It might work better for the OP if you didn't use $f$ in both examples, and if you wrote the differentiation as an operator rather than with the prime.

comment Is it correct to say gcd$(r, 0)$? The definition says greatest common divisor of nonzero integers.
Read a little more carefully. The definition says "not both zero".

comment Multiplying inverse matrices easily.
When $A$ and $B$ don't commute you need $(AB)^{-1} = B^{-1}A^{-1}$. Since you put on socks before shoes you need to take off shoes before socks.

comment Intersection of cone and cylinder layout formula for sheet metal application
A search for intersection of cone and cylinder finds many web pages. Some of them may answer to your question, either with a formula or a method for laying out the desired curve.

comment Gödel's Incompleteness Theorem and Numerical Analysis
@Adam You ask if Godel's incompleteness theorem has significant applications to numerical analysis. I tried to explain (in general terms) why I don't think it does. Perhaps you'll find other answers more helpful
