Question

Find the vector v with the given magnitude and the same direction as you. Magnitude of v = 4, direction u = <1,1>

Answer 1

<4,4>

Answer 2

that aint it lol

Answer 3

It must be a 1:1 ratio?

Answer 4

<4cos(45), 4sin(45)>

Answer 5

Is there a formula or is it a guess?

Answer 6

that is the answer; to get normal looking numbersl just plug it into a calculator

Answer 7

\[<2\sqrt{2},2\sqrt(2)>\]

Answer 8

i know the direction is 45 degress (1,1)

and the length of the thing is 4; so i used trig :)

Answer 9

But what if magnitude is 2 and direction <sqrt(3),3>?

Answer 10

compute the unit vector along u

Answer 11

then multiply it by 2

Answer 12

thats what...30 or 60 degress?

Answer 13

<2cos(60), 2sin(60>)

Answer 14

yeah ur right

Answer 15

Excuse me, I need to go to class. Thank you.

Answer 16

suppose C is a 3x3 matrix such that det(C
)=2. then det(C+C) is equal to????? PLEASE, help!!
