Hello, my name is Matthew. I am not very strong in mathematics. In fact, I am working as an artist right now.

I was wondering if any patient and helpful people could maybe give me a simple explanation of why this equation gives me the straight wall (that seemingly extends into infinity) pictured above. I am sure the reason is quite simple, but I am intrigued visually and conceptually by this effect.

Any kind of reply would be great. Thanks!

Look forward to at least learning from the forums,

M
