Trigonometry
The area of mathematics called trigonometry focuses on triangles, with particular emphasis on the relationships among the sides and angles of a triangle. The six trigonometric functions are defined in this branch of mathematics, and the applications of those trig functions carry fundamental importance in science. The cyclical (periodic) nature of sine waves, for example, model everything from atomic vibrations to light waves.
A basic course in trigonometry will cover the following topics:
 THE SIX TRIGONOMETRIC FUNCTIONS
 RIGHT ANGLE TRIGONOMETRY
 RADIAN MEASURE
 GRAPHING AND INVERSE FUNCTIONS
 IDENTITIES AND FORMULAS
 EQUATIONS
 TRIANGLES
 COMPLEX NUMBERS AND POLAR COORDINATES
 EXPONENTIAL AND LOGARITHMIC FUNCTIONS
Students can find many books on trigonometry from Google Books and Amazon.com. There are also quite a few trigonometry tutorials available, including ones from Clark University, United Arab Emirates University, 1728 Software Systems, Nipissing University, and Clemson University. Students can also follow the Journal of Trigonometry.
To fulfill our mission of educating students, our online tutoring centers are standing by 24/7, ready to assist students who need extra practice in trigonometry.
