Find the linear approximation of the function
Use L(x) to approximate the numbers
Suppose I have the linear equation
Apparently the answer is no, but I am unable to find a counter-example. If anything, my reasoning (below) tells me W is a subspace.
Problem: A metal plate whose temperature at the point (x,y) is given
Problem 1: Compute
Problem 2: Denote the position at time t by
Question 2: not sure how to proceed.
