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.

Krista, Sal, Grant, and Patrick: our Calculus saviours.
You know you're a nerd when you recognize all of these names instantly.
Who is Grant?

@@CDinkle Thanks, I looked him up. Lots of views!
what about OrganicChemistryTutor
You're so articulate and very precise with every single detail, you're simply the best!
Thank you so much, Joe, I'm so glad you've been enjoying the videos! :)
This was the video I was looking for. Thanks a lot.
Thank you! Very Clear!
You are an amazing teacher!!! Thank you for your videos!
I'm so glad they're helping!
the center point for the last quadratic equation should be (2,-1,1)
YOU ARE RIGHT TO SAY!!!!!!!!!!
why the ellipsoid we disregard the (-) sign so it becomes (x,y,z) from h,k,l , meanwhile the last one we take into account the (-) I still don't understand that part.
5=THank you sire
How can we get the picture you use?
45 years after learning Completing the Square,it's actually applied! Bravo Krista!
Great video! where can I find the full chart?
Awesome explanation! Never understood it until now.
+Hayley Williams I'm so glad it finally makes sense!
Excellent! I get it now. Wish my professor explained it as good as you! Great lecture!
+N Harvey Awesome! Glad I could help.
Thank you! Your videos are saving my life
So glad they're helping!
I'm having trouble writing the equation on a quadric surface that is defined as having the same distance from a point, P (-1,0,0) and the plane x=1. I know that it's a parabaloid centered on the x-axis in the negative direction. Any suggestions?
Awesome video. Thanks!
Thank you!!
how can i get acopy of the cheat sheet?
Great explanation, from an Italian student! Made my life a lot easier
Yay! I'm glad I could help!
this was so helpful thank you!!! I was wondering where I can get that exact chart you use because it's a lot simpler than most I've seen thanks :)
It's from my Vectors course on CalculusExpert. If you send me a private UA-cam message with your email address, I can send it to you.
Girl i love you thank you so much!
You're so welcome, Pedro, I'm so glad this helped! :D
I've a problem when additional term in the equation gets introduced like "equation 3rd + 2xy".. how to go through with that?.. ty
Thank you so much your are the best
thanks a lot. that was helpful 🙂
You’re welcome, I’m so glad it helped!! 👏
Thank you. You are awesome.
You're welcome! Glad it could help.
what do u do when u have xy, xz, and yz..... x^2 + y^2 - 3z^2 - 6xy +2xz+xyz-4x-4y+4z=5
It's good as far as it goes and I love your videos, but I wish that you would add the procedure for drawing these figures, like finding the intercepts, etc. So we would both be able to identify the figure from the equation and know how to draw it.
Great suggestion, I'll look at trying to make a video like that! :)
@@kristakingmath thanks. Finishing a course in vector analysis and your videos are always very helpful.
You are the best.....
where can I get this chart ?
Thank you so much......how can i also get a copy of the cheat sheet?
aslam9833785044 It's in my Academy now, but if you send me a private UA-cam message with your email, I'll send it to you.
This doesn't show how to eliminate xy yz and yz to make a new form.
Could you please upload this one?
A*x^2+B*x+C*y^2+D*y+E*z^2+F*z+G*x*y+H*y*z+I*x*z+J=0?
Please provide us the table , will be thankful ❤️
You made it so easy as always.
The term now is do it like Krista. Lol
:D
8 year later, thank you :)
thank you so much!! My lecturer taught this part perfunctorily so i couldn't even understand a bit before watching your videoo :(( Hate Vietnamese Universities :(((
You're welcome, Cherry, I'm so glad it helped! :)
Sketching the other 3 quadric surfaces would be more instructive. American 🏈 is an ellipsoid. What is a metallic fuel tank with two elliptical bases called?
OMGGGGGGG her voice is soo sweat
What level of math is this ?
I'm studying this in Highschool :D ?
It's Algebra, but I didn't hear about quadric surfaces until I started taking Multivariable Calculus.
Kids are going to be kids smh
