Worked example
Operation: Cross product a: 1 0 0 b: 0 1 0
→ 0; 0; 1
Method and scope
Enter two or three components. Projection is of a onto b; cross product needs three dimensions. Zero vectors cannot be normalized or used to define an angle. Choose degrees or radians explicitly.
a·b=Σaᵢbᵢ; cos θ=(a·b)/(‖a‖‖b‖); proj_b(a)=(a·b)b/‖b‖²
Precision and limits
≈ marks an approximation. Display rounding does not change the internal calculation.
