Course Learning Goals
Students will:
- analyze calculus-related concepts, such as limits, tangent to a curve, and the difference quotient; L
- apply the properties of functions, such as finding the domain and range, determine zeros of functions, symmetries of a function, vertical, horizontal, and oblique asymptotes, use limits to determine end behavior of a function, develop the skills to graph functions, and accurately use a graphing calculator to find transformations of graphs;
- perform operations of functions - addition, subtraction, multiplication, division, composition, find and graph inverse functions, solve problems involving maximizing and minimizing a quadratic function, and construct mathematical models with functions using real-world applications or formulas;
- graph exponential and logarithmic functions, accurately use the properties of logarithms and the definition of e, solve exponential and logarithmic equations, and application problems using exponents and logarithms;
- define trigonometric functions, using the unit circle and right triangle definition, graph trigonometric functions, find the inverse trigonometric functions, verify trigonometric identities and formulas, solve trigonometric equations and solve problems, using real-world applications;
- develop the ability to analyze, interpret, and apply quantitative information [Quantitative Literacy].

Assessment Methods for Course Learning Goals
Students apply mathematical concepts and principles to identify and solve problems presented through informal assessment, such as oral communication among students and between teacher and students, and formal assessment using open-ended questions reflecting theoretical and applied situations.
A minimum of 70% of a student's grade must be determined from proctored assessments and work. These proctored assessments include tests, quizzes, departmental final exam, or other proctored in-class assignments.
The final exam must be at least 20% of the course grade. Study guides, formula sheets, and other aids may not be used on the final exam.
