- Cross[ <Vector> , <Vector> ]
- Cross[ <Vector u> , <Vector v> ]
- Calculates the cross product of u and v.
- 範例:
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.
- 範例:
Cross[{a, b, c}, {d, e, f}]
yields {b f - c e, -a f + c d, a e - b d}.
備註:
- In the Input Bar you can use
u ⊗ v
