Solved Find the derivative R'(t) and norm of the derivative.
This notion of derivative is a generalization of the ordinary derivative of a function on the real numbers since the linear maps from to are just multiplication by a real number. In this case, is the function Properties A function differentiable at a point is continuous at that point.

How to find the derivative of a norm? Derivative a Norm: Let us consider any vector v → = ( v 1, v 2) in R 2 Then the ℓ 2 norm of the given function is represented as: ‖ v → ‖ = v 1 2 + v.

The derivative of a vector-valued function can be understood to be an instantaneous rate of change as well; for example, when the function represents the position of an object at a given point in time, the derivative represents its velocity at that same point in time. We now demonstrate taking the derivative of a vector-valued function.

However, it is far easier to differentiate this function by first rewriting it as f(x) = 6x − 2. f′ (x) = d dx( 6 x2) = d dx(6x − 2) Rewrite 6 x2 as 6x − 2. = 6 d dx(x − 2) Apply the constant multiple rule. = 6( − 2x − 3) Use the extended power rule to differentiate x − 2. = − 12x − 3 Simplify.

The Gateaux derivative of k · k at vin direction of uis defined as lim t→0 kv+tuk −kvk t. We say k · k is Gateaux differentiable at 0 6= vif and only if for all u∈ V, lim t→0 kv+tuk−kvk t exists. A concept related to the Gateaux derivative of norm function is the subdifferential set of norm function (see [9]). The subdifferential set

Subject classifications. Let X and Y be Banach spaces and let f:X->Y be a function between them. f is said to be Gâteaux differentiable if there exists an operator T_x:X->Y such that, for all v in X, lim_ (t->0) (f (x+tv)-f (x))/t=T_xv. (1) The operator T_x is called the Gâteaux derivative of f at x. T_x is sometimes assumed to be bounded.

This norm can be defined as the square root of the inner product of a vector with itself. A seminorm satisfies the first two properties of a norm, but may be zero for vectors other than the origin. [1] A vector space with a specified norm is called a normed vector space.
