DEVELOPMENTAL STUDIES (DS)   DS 014 Writing 3 cr An examination of the sentence and paragraph. Students will review basic grammar, engage in structural analysis of the sentence, examine various techniques to achieve coherence at the paragraph level, and ultimately demonstrate these skills in writing (ranging from shorter assignments to the essay). The course emphasizes grammatical competence, sentence style, and paragraph development.   DS 081 Prealgebra 4 cr A study of the topics from prealgebra and basic algebra skills including operations with whole numbers, fractions, and decimals; ratio and proportion, percent, and measurement; introduction to exponents, language of algebra, signed numbers, absolute value, order of operations, linear equations and inequalities, graphs and statistics. Required labs. Prerequisite: Placement test.   DS 082 Introductory Algebra 5 cr This course combines topics in pre and elementary algebra including operations with whole numbers, fractions, decimals, percents, exponents, signed numbers, order of operations; ratio and proportion; measurement; functions; solving and graphing linear and quadratic equations and inequalities; operations with polynomials, and factoring polynomials. Requires 5 hours of in-class work and 1 hour of labor work. Prerequisite: Math placement test.   DS 083 Elementary Algebra 4 cr A study of the topics from elementary algebra including the language of algebra, signed numbers, order of operations, linear equations and inequalities, graphs and functions, algebra of polynomials, factoring polynomials, fractions of algebra, linear equations in two variables, and quadratic equations. Required labs. Prerequisite: Placement test or successful completion of DS 081.   DS 084 Intermediate Algebra 4 cr A study of the topics from intermediate algebra including compound inequalities, absolute value equations and inequalities, radicals, rational exponents, operations of radical expressions, radical equations, complex numbers, solving quadratic equations, nonlinear inequalities, graphs of quadratic functions, inverse functions, exponential and logarithmic functions, arithmetic and geometric sequences, series, partial sums, binomial theorem, graphs of parabola, circle, ellipse, hyperbola, nonlinear systems of equations, nonlinear systems of inequalities.
