1.1 INTRODUCTION
• This section has been greatly enhanced, and tailored to meet our engineering requirements.
• The section outlined here is not intended to teach the elements of mathematics, but it is designed to be a quick reference guide to support the engineer required to use techniques that may not have been used recently.
• For those planning to write the first ABET Fundamentals of Engineering exam, the following topics are commonly on the exam.
- quadratic equation
- straight line equations - slop and perpendicular
- conics, circles, ellipses, etc.
- matrices, determinants, adjoint, inverse, cofactors, multiplication
- limits, L’Hospital’s rule, small angle approximation
- integration of areas
- complex numbers, polar form, conjugate, addition of polar forms
- maxima, minima and inflection points
- first order differential equations - guessing and separation
- second order differential equation - linear, homogeneous, non-homogeneous, second order
- triangles, sine, cosine, etc.
- integration - by parts and separation
- solving equations using inverse matrices, Cramer’s rule, substitution
- eigenvalues, eigenvectors
- dot and cross products, areas of parallelograms, angles and triple product
- divergence and curl - solenoidal and conservative fields
- centroids
- integration of volumes
- integration using Laplace transforms
- probability - permutations and combinations
- mean, standard deviation, mode, etc.
- log properties
- taylor series
- partial fractions
- basic coordinate transformations - cartesian, cylindrical, spherical
- trig identities
- derivative - basics, natural log, small angles approx., chain rule, partial fractions
1.1.1 Constants and Other Stuff
• A good place to start a short list of mathematical relationships is with greek letters
• The constants listed are amount some of the main ones, other values can be derived through calculation using modern calculators or computers. The values are typically given with more than 15 places of accuracy so that they can be used for double precision calculations.
1.1.2 Basic Operations
• These operations are generally universal, and are described in sufficient detail for our use.
• Basic properties include,
1.1.2.1 - Factorial
• A compact representation of a series of increasing multiples.
1.1.3 Exponents and Logarithms
• The basic properties of exponents are so important they demand some sort of mention
• Logarithms also have a few basic properties of use,
• All logarithms observe a basic set of rules for their application,
1.1.4 Polynomial Expansions
• Binomial expansion for polynomials,
