Basic Vector Arithmetic
Magnitude of a Vector
The magnitude of a vector can be thought of as the size or the length of the vector. Given that a vector can be represented by an arrow on a coordinate plane then the length of that arrow would be the magnitude.
(3)\begin{align} |v|=\sqrt{v_1^2+v_2^2+v_3^2} \end{align}
This formula is given in the IB data booklet.
