Question

What is the magnitude and direction of if G(2, -2) and H(7, 6)?

Answer 1

magnitude: 9.43 units; direction 32.01°

magnitude: 6.4 units; direction: 57.99°

magnitude: 9.43 units: direction: 57.99°

magnitude: 6.4 units: direction: 32.01°

Answer 2

?????????

Answer 3

why not use length of a line formula ?

Answer 4

Whats the formula then

Answer 5

that is the distance between 2 points ., using that you can find the mag

Answer 6

OOOOOO the distance formula lol

Answer 7

yea and you can also ., use the gradient formula :)

Answer 8

to find the direction you kno (y-y1/x-x1 ) ?

Answer 9

So the answer is

Answer 10

magnitude of a vector <a , b> => \(\bf || <a, b> || = \sqrt{a^2+b^2}\)

Answer 11

what does -> G(2, -2) and H(7, 6) <- mean? G+H => (2, -2) + (7, 6) ?

Answer 12

So whats the answer

Answer 13

well, do the magnitude calculations

Answer 14

and to get the direction of a vector => \(\bf cos(\theta)=\frac{u \cdot v}{||u||\times ||v||}\)

Answer 15

ok i found and easier way
sry i confused you with the gradient
