WebTo take the derivative of a vector-valued function, take the derivative of each component. If you interpret the initial function as giving the position of a particle as a function of time, the derivative gives the velocity vector of that particle as a function of time. As setup, we have some vector-valued function with a two-dimensional input … A "unit tangent vector" to the curve at a point is, unsurprisingly , a tangent vector … That fact actually has some mathematical significance for the function representing … WebThe derivative of T (t) T (t) tells us how the unit tangent vector changes over time. Since it's always a unit tangent vector, it never changes length, and only changes direction. At a particular time t_0 t0, you can think of … WebSo, how do we calculate directional derivative? It's the dot product of the gradient and the vector. A point of confusion that I had initially was mixing up gradient and directional derivative, and seeing the directional derivative as the magnitude of the gradient. This is not correct at all. closing midday with derryn hinch 1994
