minus-square@[email protected]linkfedilinkEnglish13•6 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- = -∞
minus-square@[email protected]linkfedilinkEnglish16•6 months agoSpeaking as a mathematician, it’s not really accurate to call that -0.

When 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.
