Online algebra calculator that allows you to calculate the magnitude of three dimensional vectors with the given vector coordinates.
The magnitude, or length of a vector is denoted by two vertical stripes on either side of the vector: |V|. It can be calculated with Pythagoras' theorem. For those of you that don't know or forgot it:
|V| = square-root ((Vx)2 + (Vy)2 + (Vz)2)
A vector with magnitude 1 is called a unit vector (see below).
