Subtraction of vectors

Calculator for subtracting two 4-dimensional vectors

Calculate vector subtraction

This function subtracts two 4-dimensional vectors. To perform the calculation, enter the vectors that are to be calculated and click the Calculate button. Empty fields are counted as 0.

The following formula is calculated

\(\displaystyle\left[\matrix{x1\\y1\\z1\\w1}\right] - \left[\matrix{x2\\y2\\z2\\w2}\right] = \left[\matrix{x1-x2\\y1-y2\\z1-z2\\w2-w1}\right]\)

Description of vector subtraction

Vectors can be subtracted by subtracting the individual elements. However, vectors can only be subtracted if the number of dimensions and their direction (column or row-oriented) are the same.

The following vectors can be subtracted. They have the same number of elements and direction.

The vectors \(\left[\matrix{X_a\\Y_a}\right] - \left[\matrix{X_b\\Y_b}\right]\)     and    \(\left[\matrix{X_a\\Y_a\\Z_a}\right] - \left[\matrix{X_b\\Y_b\\Z_b}\right]\) can be subtracted.

The following vectors cannot be subtracted because they have different numbers of elements.

The vectors \(\left[\matrix{X_a\\Y_a}\right] - \left[\matrix{X_b\\Y_b\\Z_b}\right]\) cannot be subtracted.

The following vectors cannot be subtracted because they have a different orientation.

The vectors    \([X_a\;Y_a\;Z_a]- \left[\matrix{X_b\\Y_b\\Z_b}\right]\) cannot be subtracted.

Example

\(\left[\matrix{a\\b\\c}\right] - \left[\matrix{x\\y\\z}\right] = \left[\matrix{a-x\\b-y\\c-z}\right]\)
\(\left[\matrix{10\\20\\30}\right] - \left[\matrix{1\\2\\3}\right] = \left[\matrix{10-1\\20-2\\30-3}\right] =\left[\matrix{9\\18\\27}\right] \)

Further information on vector subtraction can be found in the RedCrab tutorial.
