Question

In the rectangle OABC, Vector i and vector J are unit vectors where vector I is in the direction of OA and vector J is in the direction of OC. OA = 4 and OC = 5

Find the vector expressions for OA, OB, BC, and CA in terms of Vector i and vector j

Find unit vectors in the direction of OB, CA, and CO and express these unit vectors in terms of i and J

Answer 1

OA = 4i
What is OB?

Answer 2

Sorry OC?

Answer 3

is this drawing correct?

Answer 4

Notice that OB=OA + OC

Answer 5

BC =-CB =-OA

Answer 6

CA =CO+OA

Answer 7

Can you finish it?

Answer 8

What is unit vectors?
and vector expressions

Answer 9

that is drawn right

Answer 10

a unit vector is a vector of length 1

Answer 11

i and j point in the positive x and y respectively and each have length 1

Answer 12

can you give an example?
