Homework Help: Vector Notation Question

  1. Jul 22, 2011 #1
    What' the proper way to write vector notation? For a force...
    (10 N)i + (5 N)j + (6 N)k
    or are the brackets not standard and I can just go like this when I can indicate the superscript arrow above the unit vectors
    10 Ni + 5 Nj + 6 Nk
    I'm not exactly sure and was hoping someone could tell which is correct

    My physics textbook had, for instance, a velocity written as [itex]5.0 \hat{i} + 3.6 \hat{j} - 8.4 \hat{z}[/itex] m/s. That is, numbers followed by unit vector letters with hats on them and after all three, the unit.
