the vector obtained by calculating the definite integral of each of the component functions of a given vector-valued function, then using the results as the components of the resulting function derivative of a vector-valued function the derivative of a vector-valued functionr(t)r(t)isr′(t)=...
Vector-valued functions are also written in the form r(t)=⟨f(t), g(t)⟩ or r(t)=⟨f(t), g(t), h(t)⟩r(t)=⟨f(t), g(t)⟩ or r(t)=⟨f(t), g(t), h(t)⟩. In both cases, the first form of the function defines a two-dimensional vector-valued funct...

Vector functions of the form F : R n → R n occur in so many applications that a special name is given to them. These are called vector and scalar fields. A vector field is a vector valued function F, whose domain and range are both subsets of R n . A real valued function f :...

It’s a vector (a direction to move) that Points in the direction of greatest increase of a function (intuition on why) Is zero at a local maximum or local minimum (because there is no single direction of increase) The term "gradient" is typically used for functions with several inputs...

The reason why we define the gradient vector as a row vector is twofold: (1) First, we can consistently generalize the gradient to vector-valued functions f:Rn↦Rmf:Rn↦Rm (then the gradient becomes a matrix). (2) Second, we can immediately apply the multi-variate chain rule without...
