List result xyz top to bottom
result.x =
result.y =
result.z =
Fill out xyz pattern left to right
result.x = a.y * b.z
// Repeat xyz pattern
result.y = a.z * b.x
result.z = a.x * b.y
Flip the right side of the equation, subtracting it
result.x = a.y * b.z - a.z * b.y
result.y = a.z * b.x - a.x * b.z
result.z = a.x * b.y - a.y * b.x
thanks! This will help me in my EE physics class
