Question

Find the specified vector or scalar.

Answer 1

u = -4i + 1j and v = 4i + 1j; Find ||u+v||

Answer 2

I suppose here we have to find the magnitude of the absolute value or the reverse!
First just add the 2 vectors
-4i + 1j + 4i + 1j
||2j||
So magnitude is 2 units!
I think that IS how you do it!
@Preetha ?

Answer 3

You got the answer correct, kinda.....and I think by accident, haha.

Answer 4

im not sure i basically got at the end 0i + 2j and just wanted to make sure the answer was 2

Answer 5

It is 2 because 0i is a zero vector which does not exist in this case!!
So yeah...2 is the answer!! :D

Answer 6

It is 2. Ill show ya what you do, though. The magnitude of a vector is basically its length. Here is just a vector I invent to show you a picture:
