    Appreciating that all trigonometric functions are continuous over their domains. Because of that, a limit to a point in a trig function's domain will be the value of the function at that point.

    Sometimes I look at Khan Academy videos in my subscription box and think, "Hasn't Sal covered this topic 7 times already?" I still watch, regardless.

      in the unit circle it's (0,1)

      It's graphic is going to near of Y (infinity), but it won't touch the Y in the end of the this approach

      It's an ancient comment, but just in case anybody stumbles upon it - one must differentiate between Real Numbers (where ∞ isn't a valid element) and Expanded Real Numbers (Where ∞ *is* a valid element and in certain contexts can be treated as number). In the former, way more common set, division by 0 is undefined, in the later it's precisely +∞. The answer depends on the context

      Correct, and all these years later the math makes more sense

    I think the previous pointer was fine, this one seems a little too big.

    i dislike that pointer, it reminds me of a reticle. It's also very distracting.

  • @midnightsilverpuppy

    How do you know if / when a point is in a specific domain?

    00:35 " all trig functions are continuous over their entire domain " what about f(×)=tan(×)

    • @JellyfishManiac
      @JellyfishManiac Месяц назад

      yes. the asymptotes are not part the domain for the tangent function
