Description
Essential Mathematical SkillsEssential Mathematical Skills by S Barry and S Davis covers the main areas of mathematics used in the first years of a typical engineering, science, or applied mathematics degree. This is not a textbook. It is a concise guide to what the important skills in mathematics are: the ones that need to be remembered. This second edition also includes the essential elements of MATLAB and Maple, the two most common computer tools used by students at university.

Holding up well.
Pattern Name: Checkered
Seems to be holding up to my aggressive chewer. I have it hanging from a tree branch and she loves leaping to get it! Buying another pair so she has a greater selection around the backyard.
