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?!”

You're very welcome! Thank you so much for watching!! :)

[kristakingmath]

You're welcome! And thank you so much for such a kind comment... it makes me so happy to know that the videos are helping!! :)

[kristakingmath]

Thanks for the feedback. This video is a couple of years old. Hopefully things have improved since then.

You are a gem. When you said at the beginning of the video "This is our first Euler question" I shouted "ME TOO" :D Thanks a lot, your awesome !

[kristakingmath]

@TheDiveL1 I'm happy to help! Thanks for the comment :)

[kristakingmath]

@fermionsbosons Haha, I wasn't even thinking about physics or engineering... I was just trying to illustrate how to do the calculation! :)

[kristakingmath]

@Horsefording Hi! :) You've got a great point... My tutoring background is mostly with students who were more concerned with passing their class than understanding the context behind the problem, so I think I tend to approach problems from that angle, and you're right, I TOTALLY ned to start adding more context!! Thank you so much for the great feedback and for your support! :) I really appreciate it! :)

[Tallbartender]

I want to thank you for making sense of this for me. I've been struggling to figure out what to plug in for t and y, and you explained it where no other teacher or book did. Thank you so much!!

[peteradawson]

Yes.
An example to show what I mean.
If the independent variable is t (ie time) then calculating with positive values allows one to predict future values for the dependent variable but if one uses negative values one can calculate past values.

[kristakingmath]

@rugbyboi Thanks! And yes, I will work on Fourier Series and Z Transforms! :)

Krista, I just wanted to thank you SO much for this video. My friend and I struggled for about 2 hours trying to understand what this horribly written book was trying to tell us with no luck. Our professor is incomprehensible and even our friends who had taken diff eqs were not able to help, as they had not covered this topic before. So once again, THANK YOU for such a clear and methodical approach and explanation! =)

[kristakingmath]

I'm so glad I can help along the way! :) The videos that aren't linked haven't been made yet, but it gives you an idea of what's coming up. :)

Just wanted to say thank you for all your videos in Cal II. I had an A in the class by constant practice and your helpful video. I am glad I had You (Krista), Patrick and this other MIT lady (Christine's) videos. Thanks once again and happy holidays.

[kristakingmath]

@Ghaiyst Geez! You think I look insane? That's harsh! :) Actually, saying the same thing over and over doesn't bother me at all. I love this stuff and I love making more videos, even if I do sometimes say the same thing over and over again. I just hope this helped you understand it better! :)

Some people have made the comment that it is pronounced "Ouy-ler" which is the correct Germanic pronunciation and is pronounced this way in most collegiate realms dealing with mathematics, but to English speaking people, following the rules of grammar, it looks to be pronounced Euu-ler. The semantics are correct, even if she does pronounce it differently.

[Tallbartender]

you are so sweet and smart! I love how you explain things in plain English!

[kristakingmath]

No, I'm not a teacher. These videos take some time to make, but actually posting them is not very difficult. :)

[kristakingmath]

Sometimes it's taught in a calc II course, sometimes in calc III. :)

[davidbusler]

Love these videos. Please keep posting these videos. You're doing a great job. You're helping an older student (I'm usually older than the person teaching the class).

BTW: 0Any snitty little twerp who would dare come up to me and say: "Uh, it's pronunced "oiler", not "you-ler", gets a verbal kick to the grundle and sent on their way.

[kuchh_lamhe]

One of the best videos I got on Euler's method...Thanks
