How to use it
Enter the vector components (leave z blank for 2-D).
Enter coordinates as whole numbers, decimals or fractions (3/4). Show the working gives the formula with your numbers.
Key facts
a + b = (a_x + b_x, a_y + b_y, a_z + b_z)
Components
Enter the x-, y- and (optionally) z-components; leave z blank for vectors in a plane.
Questions
How is the vector addition worked out?
a + b = (a_x + b_x, a_y + b_y, a_z + b_z)
Can I use fractions?
Yes, such as 1/2 or -3/4.
Formulas
a + b = (a_x + b_x, a_y + b_y, a_z + b_z)

Limitations
- Vectors have two or three components (leave z blank for 2-D).
- Earth distances assume the WGS 84 ellipsoid (sea level).
