Is there a way to express a function with a jump discontinuity by only using elementary functions?
...without breaking it up as a piecewise function. Can it be done with just one general expression? If so, do you have an example? If not, do you have a proof, or at least an explanation?
Thanks.

Yes, there is a way to do it. It can be done in what is called a Fourier Series. Basically a Fourier Series is a sum of sines and/or cosines. It is not gonna look exactly like the function with a jump discontinuity, but it will be a very good approximation.
