Comment on near zero
agamemnonymous@sh.itjust.works 4 months 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- = -∞

Speaking as a mathematician, it’s not really accurate to call that -0.

Yes, but it is infinitesimally close.

You also can’t call something infinity. People call stuff names. It is just important that they define their terms well enough.
