Question

Problem 7. a) Let $E \subset \mathbb{R}^n$ be an open set. Write down what it means for a function $f: E \to \mathbb{R}^m$ to be differentiable at $x \in E$. b) Let $L(\mathbb{R}^n)$ denote the space of $n \times n$ real-valued matrices, and define a map $s: L(\mathbb{R}^n) \to L(\mathbb{R}^n)$ by $s(A) = A^2$. Compute the derivative $s'(X)$ of $s$ at the point $X \in L(\mathbb{R}^n)$. What is the domain and codomain of $s'(X)$?

Problem 7.
a) Let E ⊂ℝ^n be an open set. Write down what it means for a function f: E →ℝ^m to be differentiable at x ∈ E.
b) Let L(ℝ^n) denote the space of n × n real-valued matrices, and define a map s: L(ℝ^n) → L(ℝ^n) by s(A) = A^2. Compute the derivative s'(X) of s at the point X ∈ L(ℝ^n). What is the domain and codomain of s'(X)?

Step 1

Step 1: For a function f : E → R^m to be differentiable at a point x ∈ E, it means that there exists a linear transformation A : R^n → R^m such that the following limit exists: lim(h→0) ||f(x + h) - f(x) - A(h)|| / ||h|| = 0 Show more…
