When working in 3D, the problem is simplified if we represent the vectors in Cartesian Vector Form (CVF)
Given point A (5, 8, 8)m. To check, always "walk" it!
a) Draw the vector OA.
b) Label Ax, Ay, Az.
c) Find the Magnitude of A.
a) and b)
c) magnitude for A (is the length from O to A):
A = sqrt(52 + 82 + 82) = 12.4 m
Magnitude: OA=12.4m
