(ai+bj)+(ci+dj) =(a+c)i+(b+d)j then to find the magnitude of that sum you do \[\sqrt{(a+c)^2+(b+d)^2}\]

then add the j-components 1+1=?

\[u+v=(-4+4)i+(1+1)j\]

1+1= 2 and -4+40

sorry -4+4=0

opps i read that wrong my apologizes

you could have also used the formula above \[\sqrt{0^2+2^2}=\sqrt{0+4}=\sqrt{4}=2\]

but yeah 2j is just 2 units away from the origin
freckles
  • freckles
nj where n is a real number is just |n| units away from the origin
freckles
  • freckles
magnitude is just concerned how far something is from the origin
