Homework Statement
Let ##\left\{(x_1,x_2) \in \mathbb{R}^2: 0 \leq x_1 \leq 1 \; \text{and} \; 0 \leq x_2 \leq 1\right\}.## Find the support function ##\mu_s## for this set.
Homework Equations
We define the support function ##\mu_s: \mathbb{R}^n \rightarrow \mathbb{R} \cup \left\{-\infty\right\}## as ##\mu_s(p) = \inf\left\{p \cdot x: x \in S\right\}##.
The Attempt at a Solution
I know this is a square with vertices at ##(0,0)##, ##(0,1)##, ##(1,0)## and ##(1,1)##. I'll take a line that goes through ##(0,1)## and take a vector ##p## that is orthogonal to this. I get stuck after this in finding the support function
Someone please help!.
