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?!”

This video is what we like to call "undislikable".

Explained better than my professor, thanks

I tried this and I am still not getting the right answer. Are the 2 vectors you use to define the plane arbitrary or is there a specific point I need to subtract from the other two in order to get the correct vectors?

Plz help me, does IT MEAN THE VERTICES Q, P, R ARE IN COUNTER CLOCKWISE ARRANGEMENT IF WE TAKE CROSS PRODUCT AS PQ X PR. What i mean is if three points three points are given P Q and R as in the video, if they are arranged in counter clock wise order, Now WILL PQ X PR PRESERVE THE COUNTER CLOCKWISE ORDER OR BY PR X PQ

MrRabi

could you please tell me if i given two lines first one is S: x=y+1=z+2 and r: 2x=2y+2=3z+2 how do we convert this forms of lines into parametric form

Krista. Great video but I have a question, what software do you use?

marcusmiguel

What if they what two units vectors. How can I get it. ?

Thank you Krista! I love you soo much!

If you have a vector length and an equation, what do we do? Thanks for the video by the way it really helped!

Why is it incorrect to refer to vectors as "perpendicular"? What is the difference between orthogonal and perpendicular?

If you were Indian your explanation would better
