What in blazes does that mean? I would give anything to understand the language of math, but how does one even begin to learn the language? I read explanations like that and go into a state of panic, sure I must be a complete idiot, and not a happy one.

What in blazes does that mean?  In this case it's a fancy way of saying: the function describes waves.

If we were to create an exhibit for a children's science center, what picture would represent each one of these, and what the explanation be?  At the most basic level they're important because they define and predict how things  engines, generators, electric circuits, nuclear reactors,etc etc all work.
I've absolutely no idea how to answer your second question  popularizing science for children is well outside my job description.

I think the function of the keystone in a stone arch can be described by some sort of mathematical equation.
It's probably in the top ten, but don't quote me on that.

It's probably in the top ten, but don't quote me on that.  The ideal form of a freestanding arch of constant thickness is a inverted catenary, which is a permutation on a hyperbolic cosine; though these were used occasionally during the Middle ages, the mathematics and physics of these arches wasn't fully understood until the late 17th century. Most the construction in the ancient world were based on semicircular or round arches, which are less ideal, but worked well enough nonetheless.

Also in a not exactly positive way?
BlackScholesMerton model ... that is to say the equation which gave a math base [and justification] to the creation of the immense market of financial derived products ...

Give me the math, not your prejudiced opinion.  ... but all that's not really math(s) is it? .... that's just basic sums! Arithmatic. It's just adding, subtraction, division and multiplication... anyone with a modicum of basic commonsense should be able to do that. Heh ... even my dog can do addition and subtraction ... at least with units up to three: yours; mine; theirs.
Although I do wholeheartedly agree that people should be better educated mathematically. Why is it acceptable for educated people to be able to say " Hey ... I never could do numbers" ... when one would certainly look twice at someone, supposedly Englishspeaking, saying "Shakespeare ... err who?", or "I kant do spelin". Although when the British Minister for Education can say something along the lines of "It's an outrage ... half our children are performing below average!", I despair. (And yes I am well aware of the difference between the mean, median and mode ... although I'm not sure Her Majesty's Minister is).

And yes I am well aware of the differance between the mean, median and mode ... although I'm not sure Her Majesty's Minister is.  The relationship between mathematics, beauty, and religion and how these things relate to 'truth' (whatever that is) is a thread unto itself. But one thing I will say here is that Mathematics is NOT about 'verifiable truth', you're confusing it with science. Truth in Mathematics (assuming Mathematics is true, which is itself an article of faith) cannot be based in observation or experimentation, it finds it's validity in consistency, even as its consistency cannot be proven: https://en.wikipedia.org/wiki/G%C3%B...eness_theorems
