Crossing a vector with itself
Webthe criterion we have seen for a vector field to derive from a potential. And if the curl is zero then it means that this force does not generate any rotation effects. For example, if you try to understand where the earth comes from, well, the earth is spinning on itself as it goes around the sun. And you might wonder where that comes from.

WebFeb 28, 2010 · If the boat is pointing at an angle θ to the current, then we draw a vector triangle of the velocities: 5 along the current, followed by 12 at an angle θ, making the third side (length V at an angle φ say) representing the resultant velocity (relative to the ground). Obviously, 12sinθ = Vsinφ = 1500. The time taken is distance/speed ... WebThe length of the cross product of two vectors is directly proportional to the length of each vector as well as the sine of the angle they span. In the first case, the angle spanned between a vector and itself is $0$, and $\sin(0)=0$, so that we obtain a vector of length …
