# Three Dimensional Vector Calculation

Calculate the magnitude of three dimensional vectors (3D Vectors) for entered vector coordinates.

Vector A: | |||

Magnitude:

The 3D vectors are using the x-y-z axes.
The vector OP has initial point at the origin O (0, 0, 0) and terminal point at P (2, 4, 5). So we can draw the vector OP .
We saw above that the distance between 2 points in 3-dimensional space is
distance AB=√(x2−x1)

^{2}+(y2−y1)^{2}+(z2−z1)^{2}So we can drawn the vector A or say OP .

We saw above that the distance between 2 points in 3-dimensional space is distance AB=√(x2−x1)

^{2}+(y2−y1)

^{2}+(z2−z1)

^{2}

Since we assumed originating point O as (0,0,0) and terminal point at P (2, 4, 5) for the vector A, therefore the magnitude of the vector is given by:

∣OP∣=√2

^{2}+4

^{2}+5

^{2}

= √4+16+25

=√45

= 6.708 units
