    Hi, I’m Krista! I make math courses to keep you from banging your head against the wall. ;)
    Math class was always so frustrating for me. I’d go to a class, spend hours on homework, and three days later have an “Ah-ha!” moment about how the problems worked that could have slashed my homework time in half. I’d think, “WHY didn’t my teacher just tell me this in the first place?!”
    So I started tutoring to keep other people out of the same aggravating, time-sucking cycle. Since then, I’ve recorded tons of videos and written out cheat-sheet style notes and formula sheets to help every math student-from basic middle school classes to advanced college calculus-figure out what’s going on, understand the important concepts, and pass their classes, once and for all.

    This is a wonderful lecture. She had everything prepared and you could see the whiteboard as she spoke making it easier to understand, plus she presented all this material in under 10 minutes which means I could see the whole lecture in one viewing. And making me inclined to see the video a second time later to re-enforce the concepts..

  • @kristakingmath

    i'm so glad you think so! just keep practicing and working on these, and they'll definitely get easier! :D

  • @sail2byzantium
    @sail2byzantium Před 8 lety +5

    Excellent presentation! Very clear and professional (it doesn't sound at all "ad hoc" with pauses, "ums", etc. On the final graph--I understood the basics of everything you said--but am left curious (and a bit puzzled) about those limits (3 - 5) with empty and filled-in points, with the filled in point being the value of the function. Have subscribed!

    • @kristakingmath
      @kristakingmath  Před 8 lety +1

      Thanks for subscribing! It's just that the filled-in point always gives the actual value of the function, but you can still find a limit at those non-filled-in points (a general limit if it's a point discontinuity, or a one-sided limit if it's an endpoint).

    I wish I could learn all the math from someone this beautiful.. Thanks for the vid, by the way! :)

  • @kristakingmath
    @kristakingmath  Před 11 lety

    I love u too! :) Realize that tanhx=sinhx/coshx. If u check out my video on hyperbolic identities, you'll see that sinhx=(e^x - e^-x)/2, and that coshx=(e^x + e^-x)/2. When u divide the sinhx identity by the coshx identity, u get (e^x - e^-x)/(e^x + e^-x). Remember that e^-x goes to 0 if x goes to +infinity, and that e^x goes to 0 if x goes to -infinity. If u plug those values in, u get a limit of 1 as x goes to +infinity, and a limit of -1 as x goes to -infinity. Hope that helps! :)

    That was pretty good.
    Loved the overall presentation and the clear explanations.

  • @kristakingmath
    @kristakingmath  Před 12 lety

    The function simplifies to f(x)=x+2. So, when you plug in x=2, you get f(2)=2+2=4, so the coordinate point is (2,4). However, the function is undefined at that point, since plugging 2 into the original function gives you 0 in the denominator, which means it's undefined at that point. Hope that helps! :)

    Also, for the jump discontinuity, how do we know which value would be for the one coming from the left and the one coming from the right?
    For example, on a graph, will the higher value always be matched to x that approaches a from the right?

    Hi Krista, thanks for uploading all this great material. You are definitely in my top 3 favorite calculus lecturers on youtube. It's a toss up between you, patrickjmt, and mathbff. You're really good at breaking down complex ideas into their simplest terms, and you have such a sweet and relaxing voice, which puts me at ease when I'm trying to learn. By the way, the link in your description for the limits & discontinuity formula sheet appears to be broken.
