About this document

MATH 140B HW 7 Solutions Overview by jozandc is a document available to read on EtoBox.

This document contains solutions to 4 problems from a homework assignment on calculus. Problem 1 involves proving that a function f(x) has derivatives of all orders at x=0, and that the nth derivative at 0 is 0 for all n. It uses 2 claims: 1) limits of rational functions times e^-1/x^2 go to 0 as x goes to 0, and 2) the nth derivative of f can be written as a rational function times e^-1/x^2. Problem 2 involves summing the entries of an infinite matrix and proving the sums are -2 and 0. Problem 3 calc
