minus-square@[email protected]linkfedilinkEnglish13•1 year agoWhen taking about limits, you can approach 0 from the positive or negative direction, which can give very different results. For example, lim cotx, x->0+ = ∞ while lim cotx, x->0- = -∞
minus-square@[email protected]linkfedilinkEnglish16•1 year agoSpeaking as a mathematician, it’s not really accurate to call that -0.
minus-square@[email protected]linkfedilinkEnglish2•1 year agoYou also can’t call something infinity. People call stuff names. It is just important that they define their terms well enough.

Speaking as a mathematician, it’s not really accurate to call that -0.
You also can’t call something infinity. People call stuff names. It is just important that they define their terms well enough.
Why do you think that?
Yes, but it is infinitesimally close.
