Why is this on the front page? What's significant about it?

Not sure why this is on the front page either though in my college engineering coursework, we did use these function to write out piece-wise continuous functions. These function might be the input signal to an electrical circuit or the load distribution on a building beam we were analyzing.

For example, using a heaviside function, you could analyze what happens to a power supply when the switch is turned on at time t=0.

Somewhat niche knowledge as I haven't really used it in the last 10-20 years but it was interesting to learn.

Sorry, I wasn't asking what's interesting about delta functions -- I've used them as well. I was asking about the document and what's significant about it, since it seems quite incomplete (?) and hardly goes into any depth (or breadth for that matter)... there are lots better ones out there so I'm confused why anyone posted this.

Here's some interesting reading about a more rigorous treatment of the Dirac delta: https://en.m.wikipedia.org/wiki/Dirac_delta_function#As_a_di...

Figure 1: oof. Vector graphics are your friend.
