Question

Let v be the vector with the initial point (0, 10) and terminal point (7, 3). Write v as a linear combination of the standard unit vectors i and j.

Answer 1

so we have to take the magnitutde and divide it by the compenent parts to get the unit vector parts

Answer 2

move the points by (0,-10)

(0, 10) (7, 3)
(0,-10) (0,-10)
--------------
(0,0) (7,-7) ; its 45 degreeish lol

Answer 3

unit v = i - j :)

Answer 4

might be a sqrt(2) in it

Answer 5

Thanks again :)

Answer 6

unit i is 1 and unit j is 1 is how a interp it ...
