2 semesters, 1 credit (With ECC option)**Open to sophomores, juniors, and seniors****Prerequisites:** Minimum grade of B in 415 Advanced Algebra I or A in 430 Algebra II class and 1 credit in 420 Geometry or 422 Advanced Geometry and teacher approval. Note: to qualify for this course, a student must have a cumulative grade point average (GPA) of 2.5.

This class is a unified study of College Algebra and Trigonometry with particular emphasis given to preparation of the student for the study of Calculus. Topics include sets, complex numbers, logs and exponents, polynomials, rational expressions, radicals, solving equations and inequalities, graphing equations and inequalities, matrices and determinants, permutations and combinations, theory of equations, and the study of the trigonometric functions. The use of a graphing calculator and its application to the topics of Precalculus will be emphasized. This course must be taken as a prerequisite for 443 Honors Calculus. **A TI-84 graphing calculator is required for this class. ****This course may be taken for college credit** if score is high enough on ECC placement test or score on math section of ACT and a 2.5 GPA. If student elects to take this course for college credit (ECC course MT1505, 5 credits), an additional fee will apply.

By the completion of this course, students will be able to…

- Use basic trigonometry functions.
- Identify functions and their properties, algebraically and graphically, and find inverse functions.
- Solve systems of equations involving two or three variables using a variety of methods.
