Technically, 0/0 is known is an indeterminate form; it’s undefined. Other indeterminate forms are:
∞/∞
0×∞
∞ – ∞
0^0
0^∞
1^∞
As bchad mentions, if these arise as limits of functions of a single variable (and those functions are differentiable), you can sometimes use l’Hôpital’s Rule to calculate the limit. However, if you’re merely computing a ratio of two static numbers, it’s not a limit, and it’s simply undefined.
I can’t decide if you generated some deep insight by extending the analysis into the complex plane, or just ended up scattering a few random symbols into your post to make your elusive thought process even less comprehensible?
Why thank you, it is always nice to hear a word of encouragement. Let me know how your middle school algebra class did this fall. I heard there are a lot of bright students and you are an outstanding teacher
Ha ha I loved this exchange…it brought all the quants out to play! I too am of a more “fundamental” persuasion and would probably simply leap to the conclusion that the subject ratio is simply not useful for evaluating this particular financial circumstance. No doubt a different analytical angle would prove more useful!
But then again I would miss out on this scintilating Math exploration.
A few years ago I took it upon myself to learn calculus on my own. Was probably one of the best things I’ve ever studied. I def want to take some higher level maths and physics courses once I get through year-one of my current career pivoting.
