Question

Question about vectors?

* (v and w are vectors)
Given v= (4, 2) and w= (-3, 5), find the coordinates of v + w.

a. (1, 7)
b. (1, -3)
c. (7, 7)
d. (7, -3)

I got answer B. Is that correct?

Answer 1

no it's not
add each component seperately

Answer 2

v=<a, b>
u=<c, d>
v+u=<a+c, b+d>

Answer 3

That still gives me the same answer, though

Answer 4

show your work please

Answer 5

v= (4, 2) 4 is a, 2 is b
w= (-3, -5) -3 is c, -5 is d
v + w = (4 + -3), (2 + -5)
v+w = (1, -3)

Answer 6

the way you typed the problem above you have w=(-3,5), so which is it?

Answer 7

I'm sorry, it's (-3, -5).

Answer 8

then you were right all along :)

Answer 9

Haha, thank you. Sorry about that!

Answer 10

No worries, it happens to the best of us ;)
