I too am appalled at the abandonment of a solid numerical analysis
course in engineering education. Consider the common problem of solving a
set of linear, independent algebraic equations. Students have to be shown
that Cramer's rule will not work when using the (inevitable) finite
resolution of a computer or calculator.

I was never shown that, but I do remember it being drilled into our heads that
Cramer's rule was the bogosort of linear system solving -- just about the
least efficient means you could possibly choose, and that it existed primarily
because it can be useful to have a closed form solution to a system of
equations.

Numeric analysis of linear systems is an incredibly in-depth topic, as far as
I can tell. Books such as SIAM's "Numerical Linear Algebra" spends hundreds
of pages going over it all.
