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?!”

I really appreciate your explanations. I just dont know how to thank you enough for your dedication and hard work.

Thank you so much for making your video thorough and short! I have a calculus exam coming up in about 15 minutes and I realized I couldn't remember how to solve for the equations when given a graph... You just saved me and my grade lol!

[Dabagel]

Easy to follow and well explained. Thanks!

[pholarised]

Thank you very much and your voice is so calming even during the stressful times

[matthewcroy]

I'm pretty late to this but thank you! My final is today and I feel really prepared now

Is there a video where you prove your "reminder" equation?

[MinesFavorites]

You're just an incredibly positive impact upon this world. 

[aymanadel]

Which way should I use? I am confused. You have explained a way which is totally different that this one.

Very stressed when doing a review of 50 problems, you look for this and then hear her voice.
I wish she was my calculus teacher.

[earthtotracee]

you are super awesome! my calc teacher is awful and i've taught myself calc 3 from your videos!

What if we are given the endpoints of a line segment and we have to get its vector equation? How are we going to get the restriction for t?

[omiorahman]

Do you have some math /physics problems that is related with toy plane or swimming or bird movment or subamarine toy car
so that it can be used in videogames design

[amysantiago]

So the limit will always be 0 to 1 ???

[ignantxxxninja]

ok I follow this but why is there the arbitrary rule 0<=t<=1

[pedrosoto]

what happens when there are 3 vectors?

[nonichan]

Thank you, I took this last course and now forgot how to simply

[maluantonini]

is this a class for hight school or college ?

[photon]

alright cool easy, but i dont get how she got the equation she used.
