Elementary Trigonometric Equations
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 ).
- 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.
