How to Use this Applet
The Graph Area
 Drag "filled" locations in the unit circle graph ( •, • and/or • ), or the "filled" location in the function graph ( • ) to adjust the number on the right side of the trigonometric equation.
 Drag any location along the function graph towards or away from the vertical axis to change n ( of nθ ).
Other
 Use the "sin", "cos" and "tan" buttons to change to the desired trigonometric function.
 Use the "RADIANS" and "DEGREES" buttons to change between arclength along the unit circle (RADIANS) and the construct unit of DEGREES.
