Vectors 6.7 Operations with vectors in R3

Unit basis vectors i, j, k How to find the magnitude of a vector in R3, adding vectors in R3, and how to find a unit vector in R3. Basically the same operation as you did for vectors in R2 except now we have 3 variables.
I also cover questions 13 and 14 from page 332 in the Nelson textbook.

When you were making the parallelepiped, how did you know which vertices to connect?

I just had a question. 5:50, How is vector AB one coordinate on the coordinate plane. Since its a vector shouldn't there be two coordinates and you connect them? Is the first point the origin and the that point is P(a, b, c)?

how do you know which vectors to add together for the parallelepiped?

Hi miss, just to be clear since I’m having a bit of trouble with the definition google gives
A position vector always has its tail touching the origin, right?

Ms Havrot for parallel pipeds we just add all the give vectors together with each other right?

Nice video I really enjoyed it,
I also make educational videos too
