You can also use our own Graph Explorer to produce the graphs of various trig functions. (Any Computer Algebra System or Graphing Calculator would do as well of course but the detailed instructions might be a bit different.)
The effect of multiplying a basic trig function by another function to give a variable amplitude or "damping" effect is discussed at this page on the "CoolMath" site which also includes a page of other links to sites dealing with trigonometry and trig functions.
Although the trig functions are not one-to-one and so do not have inverse functions, they do have invertible restrictions and these are discussed at the UBC site on Inverse Trigonometric Functions
animation of the sine function, together with its gradient and derivative,
can be seen at Calculus
The University of Saskatchewan's "Exercises in Math Readiness" site
has these notes and exercises on Trig
Simple trigonometric equations are also dealt with at Trigonometric Equations, from the University of Texas El Paso's S.O.S. MATHematics site.
For other online material you might try this short course in trigonometry , or (especially in preparation for Math174) The Trigonometric Functions and Calculus for Liberal Arts and Business Majors, a text resource written by Stefan Waner and Steven Costenoble of Hofstra University, and OregonState's "CalculusQuest" includes a precalculus "Field Guide" to functions which includes this section on trig functions, which has been reviewed by Frank Choy.
You might also check our 'raw list' (of links provided without comment)
to see if there are any
more examples there that we haven't yet included here.
If you have come across other good web-based illustrations of trigonometry
please do let us know and we will add them here.
