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?!”

almost 8 years later and this video clarified my doubt tysm

Krista, you were a really big reason as to why I got a good grade in Calculus 2, now taking Multivariable Calc, I have a feeling you're gonna help me a lot again. Thank you for what you do!

[maximelegrand]

Perfect timing! Im actually learning things about parametric lines, plans, and all things like that, and you are posting them so nice!
A thank from France ;) I also shared your channel to my class haha!

[slinkpot]

This video is wildly helpful. Thank you very much.

[edmund]

lol, I needed help on symmetric equations and this is the exact homework problem I was stuck on

[hawkeye]

Thank you so much! If I can understand how to do the problem I can understand the subject but understanding how to do it is the hardest part. THANK YOU!

At 4:18 - 4:19 "we're going to pull out a J"
Is that in anticipation for 4:20?

Finna pass my exam thanks to this channel

[dariennesee]

Wonderful video! Thank you for giving such a clear explanation!

[noahetan]

i really appreciate what you do. thank you. thank you from deep within my heart

[thememesarealive]

thank you for explaining symmetric equations! Calc 3 teacher did not mention them and they are on my homework :(

[AlexanderMcNulty]

Whenever I need a someone to go the extra mile in explaining 'why' I come to your channel.

[gocelinedion]

You just made my day. I finally understand it!

[solarcatt]

This was so helpful, thank you so very much! Your explanations were hella thorough and I find myself understanding the processes more clearly. One question, though! Our teacher introduced the vector equation form to look like r = (xo, yo) + td. The form you have includes the i, j, and k details of a vector; are both of these forms correct for the vector eq?

[aaiyeeshamostak]

Correct me if I am wrong, as far I know, X - 2 is not an equation, it's an expression. I also did not get why we are counting it in symmetric equation. Would be grateful if you could help me to get a better insight.

If are asked to parameterise the line segment joining points (0, 1/2, 1) and (2, 1, -3). Then restriction values of parameter t will be diff if we pick the other point <0, 1/2, 1>.

your hand writing on pc is better than my hand writing on a page !!!

[KabooM]

Oh but that doesn't mean your explaining wasn't great. :D
I love the style of the chalk and the blackboard and your clear voice and accent. I can pass my test in peace now, thank you!

[markjohnson]

You’re the bomb girl. Thanks for all of these great videos.

Thank You so much
u saved me from getting F in CAL
