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?!”

best damn explanation of direction cosines and angles I've seen...thank you

[nayanjyotidas]

That voice is so pleasant to listen to!

I used to watch your videos like 10 years ago for GCSE and IB exams. A long time has passed

Brian is right. My book uses gamma also. That said, this video was still more clear than my book. Thanks for the explanation!

Can't find better content and explanation than this ☺️🙂

Uppercase upsilon looks like the Latin uppercase Y - which is just the Y we use in our alphabet. Lowercase gamma looks similar (but not exactly like) to our lowercase y. Uppercase gamma looks like a vertically flipped L, and lowercase upsilon looks similar (also not exactly) to our lowercase u. Though then this can get easily confused with lowercase mu or nu... it's tricky.

Thank you for the great tutorial of Direction cosine. Can you tell me the applications of this topic? I understand the concept, but I have a hard time understanding the real world uses of direction cosine.

[ZakKrenzer]

Great Video! Very clear and well explained. THANKS!

[sikandarali]

I forgot how to find direction cosine this video helped me thx alot

[rajeshkumararv]

Krista thank you so much fir helping ❤️

[oshinsharma]

Fantastic work! My teacher couldn't get this is my head in 2 days! Really helpful, especially when you have your exam the ext day.

This helps so much!!!
I love listening to your voice a lot more than my professor ;)

[QMallow]

You explained it very well. Thank you!

[briandasilva]

I'm pretty sure that's gamma not epsilon...

[hopejavier]

Thank you so much, I understand it better now!
