About this document
MATH6501 Problem Sheet 3 Solutions by Wilson Bethuel is a document available to read on EtoBox.
This document contains solutions to problems from a math course. Problem 1 derives the identity cosh^2(x) + sinh^2(x) = cosh(2x) by squaring and adding hyperbolic trigonometric equations. Problem 2 derives the hyperbolic trigonometric identities sinh(3x) = 3sinh(x) + 4sinh^3(x) and cosh(3x) = 4cosh^3(x) - 3cosh(x). Problem 3 finds the inverse hyperbolic cotangent of a number and Problem 4 analyzes the shape of a live cable hanging between poles.
