Editor's Note: This file was selected as MATLAB Central Pick of the Week

Interactively explore how parameters affect trigonometric functions. TRIGDEMO allows user to manipulate the parameters A,B,C,D in the general equation:

y = y(x) = A trig(Bx + C) +D

Where trig is any one of sine, cosine, tangent, cosecant, secant, cotangent.

The inspiration for this was my participation in a discussion, during the course of which, it became clear that several very educated people didn't completely (reflexively) understand how these parameters affect the plot of trigonometric functions.

I figure if these folks were hesitant, there might be others out there who could use a little refresher.

For demonstration purposes only! This is not meant to be earth-shattering.
