    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.

        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?
