1. Mathematical/Logical Reasoning
a. illustrate historical and contemporary applications of mathematical/logical
reasoning
b. clearly express mathematical/logical ideas in writing
c. explain what constitutes a valid mathematical/logical argument (proof)
d. recognize higher order problem-solving and/or modeling strategies


2. Critical Thinking
a. gather factual information and apply it to a given problem in a manner that is relevant, clear, comprehensive, and conscious of possible bias in the information selected
b. imagine and seek out a variety of possible goals, assumptions, interpretations, or perspectives which can give alternative meanings or solutions to given situations or problems
c. analyze the logical connections among the facts, goals, and implicit assumptions relevant to a problem or claim; generate and evaluate implications that follow from them
d. recognize and articulate the value assumptions which underlie and affect decisions, interpretations, analyses, and evaluations made by ourselves and others

3. Other Competencies

Mastery (these are skills that should appear and be tested on during the semester and/or on the final exam)
Solving higher order equations and inequalities
The student is expected to be able to solve:
polynomials with rational roots (know techniques of division, long and synthetic, the rational root theorem, DesCartes Rule of sign, upper/lower bounds theorem, conjugate pair theorem, and factoring).
non-linear inequalities by the use of the boundary point (sign graph) method
rational and fractional equations
radical (rational exponents) equations
exponential and logarithmic equations

Algebra of expressions the student is expected to be able to simplify forms
including polynomial, rational and fractional (including complex fractions), radical, complex, absolute value

Techniques of graphing the student is expected to know:
polynomials (intercepts, turnaround points)
rational functions (intercepts, vertical asymptotes, horizontal and oblique asymptotes)
radical (rational exponents) functions (including partial parabolas and partial circles)
absolute value functions
piecewise defined functions
exponential and logarithmic functions (general shapes)
conics
lines as a review only (includes all forms such as point-slope, slope-intercept, and standard form as well as the formulas and use of slope, parallel and perpendicular, midpoint of a line segment, and distance)
parabolas (vertex, focus, directrix, axis of symmetry, direction of opening), min/max theory and optimization techniques
circles (center, radius)
ellipses (center, major/minor axes, foci)
hyperbolas (center, asymptotes, foci, vertices)
Translations, shifts, stretches, and compressions as applied to functions
Use of the graphics calculator is generally introduced and included.

Functions and Inverse functions
The student is expected to know functional notation, to understand the difference between functions and relations and find the domain and range of a function or relation, how to find inverse functions mathematically, sketch inverses, and know relationships of domains and range for functions and their inverses.

Methods of solving systems of equations (linear and non-linear)
Included for linear systems of either two or three linear equations are techniques of substitution, elimination (or addition), and matrix methods (Gauss-Jordan elimination). An introduced technique is the matrix method of Cramers Rule and the method of determinants. Included for non-linear systems are substitution and elimination.

Algebra of functions
The student is expected to know addition, subtraction, multiplication, division, and composition of functions and their notation as well as their sketches.

Algebra of complex numbers
The student should know complex numbers and be able to relate complex numbers to the radicals with respect to addition, subtraction, multiplication, and division and also how to solve equations involving complex solutions.

Proportionality the student is expected to know how to read, set up and solve proportionality problems including direct, inverse, square, and joint
