Math 113 - Trigonometry
- Prerequisites: Advanced math competence -- algebra and suitable placement scores, or Math 112.
- Frequency: Fall (I), Winter (II), Summer (SS)
- Student Body: Math 113 is meant for those students who plan to take any calculus course needing trigonometry.
- Credits: 2. Students may not receive credit for both Math 113 and 114. (E)
- Recent Texts: "Trigonometry" by J.D. Baley and G. Sarell, McGraw Hill, revised 3rd edition
- Course Coordinator: Jean-Pierre Rosay
- Background and Goals: This course covers the graphs, properties and geometric significance of trigonometric functions of a real variable. Other topics include trigonometric equations and identities, applications, trigonometric form of complex numbers and DeMoivre's theorem.
- Alternatives: Math 112 and Math 113 are both covered by Math 114.
- Subsequent Courses: After Math 112 and Math 113 a student can enroll in Math 171, Math 211 or Math 221.
