How to Calculate Cross Product of Two Vectors in Cartesian coordinates

Definition:

In elementary arithmetic, given an equation between two fractions or rational expressions, one can cross-multiply to simplify the equation or determine the value of a variable.

Method :

Formula :

Example :

Solve 2i + 7j - 5k = 0 -3i + 8j + 11k = 0

Solution:

Hence, we get Therefore, Hence, the solution is 117i - 7j + 37k = 0
