Academics at Champion
The purpose of this class is to enable students to become proficient in introductory analytic geometry, the theory of limits, differential calculus of algebraic and trigonometric functions, applications of differentiation, anti-derivatives, and the definite integral. This course provides an excellent opportunity for the student to experience a college level mathematics course in a high school setting. Students who are interested in math and who desire to enter the math or science field will find this course challenging and very helpful in their further studies.
