Find Magnitude of a Vector

[nycmathguy]

Section 6.4

Please, work out (24) in step by step fashion. I will then do all odd numbers when time allows and check the answers for myself in the back of the book. Thank you.

24.

u=<4,-6>

the magnitude of the vector is

|u |=sqrt(4^2+(-6)^2)=sqrt(52)=2sqrt(13)

Pretty easy. I will do all odd numbers on my day off.
