2019年3月22日 · Point for you to ponder on - the cross product of two vectors gives a third vector, perpendicular to the original two vectors. Could you define a (meaningful) cross product in R^2 …

2017年7月25日 · is linear. Suppose instead we have two vectors x and y in 3 -space. Then the cross product gives us a new vector x × y that's orthogonal to the first two. Furthermore, cross …

2020年6月26日 · When I calculate a cross product of two vectors in Cartesian coordinates, I calculate something that seems like the determinant of a 2x2 matrix. Is there any connection …

2012年5月25日 · In finding the derivative of the cross product of two vectors d dt[→ u(t) × → v(t)], is it possible to find the cross-product of the two vectors first before differentiating?

The equation with sin θ sin θ can help you to find θ θ once you know the cross product, its magnitude, and the magnitudes (or norms) of a a → and b b →, but it won't help you find the …

While it is feasible to compute a cross-product in four dimensions, the cross-product only has the orthogonality property in three and seven dimensional spaces.

2015年10月12日 · This is a completely false and misleading answer. You can't expect to do linear algebra with a curvilinear coordinate system. E.g. using this determinant, a simple cross …
