    W = 4j = 0i + 4j Anything of the form W = ai + bj has the magnitude |W| = sqrt(a^2 + b^2) The unit vector of W will be (1/|W|)*W this vector will be of length 1 and it will point in the same direction as W

    do you see how 0i + 4j matches up with ai + bj making a = 0 b = 4

    yea, I can see 0i+4j=ai+bj making a=0 and b=4

    very good, <0,1> or 1j = j
