- Cross[ <Vector u> , <Vector v> ]
- Calculates the cross product of u and v.
- Example:
Cross[{1, 3, 2}, {0, 3, -2}]yields {-12, 2, 3}.
- Note: In the Input Bar you can also use
u ⊗ v.
CAS Syntax
- Cross[ <Vector u> , <Vector v> ]
- Calculates the cross product of u and v.
- Example:
Cross[{1, 3, 2}, {0, 3, -2}]yields {-12, 2, 3}.
- If a vector contains undefined variables, it yields a formula for the cross product.
- Example:
Cross[{a, b, c}, {d, e, f}]yields {b f - c e, -a f + c d, a e - b d}.
Note:
See also Dot Command.
