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?!”

She melts my heart when she says "hey everyone!!" at the beginning haha I am still learning from her even if some videos are a decade old. She's the best

I just watched a couple other videos on this by much more popular people and still had no idea but after watching your video once I completely understand. Your gifted at teaching, don't ever give it up! You alone have probably saved thousands of kids  from failing haha thank you and keep it up!

[sterlingbubolz]

this is the greatest thing ive ever seen on youtube. you actually just summed up a week of my calc class. thank you soooo much!!

[XPTPCREWX]

Theres a lot of videos on youtube that try to explain the LCT but I think this is the best one, mainly because you are thorough and spend enough time through the reasoning. Thanks for your insight!

[juhairahadji-daud]

I really like the way you teach. Out of all YouTube tutorials I've been checking out, you're the best one so far. U always manage to answer my questions in mind. Thank you so much! You're a great help with my Mathematics subjects. I do hope you'll keep on helping us 😊

This was very helpful! I'm taking a summer Calc 2 course right now. I have a final in two days, and I'm doing a lot of work with series right now. I could not really understand how to use the Limit Comparison Test until you said that you choose Bn based on what terms have the greatest effect on the magnitude of An. Thanks so much! I'm sure that I'll be watching your other series videos as well!

[caitlinswim]

Series is the first subject in calculus, or even math that I've ever struggled with. Your videos on all the different tests have helped me so much!! Thank you!

[talesofadam]

Thanks again for illuminating a complex idea with such clarity! Of all the series tests, this is the one I've had the hardest time understanding, particularly how to choose b_n.

Why can't my professor be this helpful? Thank you very much!

Thanks for quick reply; taking last test tomorrow. This will come in handy.
Have a great day!

[jasminsahota]

I really appreciate these explanations. They have helped me understand the process, step by step. So thank-you :)

[adeline]

you are the best!!..thank you so much, my best grade in calc is because of you..thank

[kristakingmath]

You're awesome! Thanks for the comment. :)

[djelite]

Great example! Love your video's :)

[WacoBeautyQueen]

What if your series is something like (2n^2-1)/(3n^2+4). What series do you compare this to? Because I know when you have 2n^2/3n^2 the powers cancel each other out so how do we fulfill all the rules of LCT?

[fredfan]

Thanks, extremely helpful. Think I now have a fighting chance in my calc exam!!

[diepus]

Sup, sup, Ms. thanks for helping me through Calc 1, 2. Noticed vids keep getting tech advanced as time goes on; from white board on floor to full-on computer use. Anyways, you mention in this vid a convergence table. Can't find on your site. If possible, please direct me to it? Gracias!!!
