Background and Goals: Covers the graphs, properties and geometric significance of trigonometric functions of a real variable. Other topics include trigonometric equations and identities, application, trigonometric form of complex numbers, DeMoivre's theorem, and polar and parametric equations. The course also has a significant number of applications, especially related to other disciplines.

Alternatives: Math 112 and Math 113 are both covered by Math 114.

After Math 112 and Math 113 a student can enroll in Math 171, Math 211 or Math 221.
