Trigonometric Applet Help Page
When the trigonometric applet starts you will be asked to use a cosine, sine or tangent equation. After this on of the following equations will appear.
f (x) = _________ * cos ( ________ X + ________ ) + _________
f (x) = _________ * sin ( ________ X + ________ ) + _________
f (x) = _________ * tan ( ________ X + ________ ) + _________
You will need to supply the program with the coefficients in the three blanks of the equation. Once this is done press the "Enter " button and the graph will be displayed in the window above the equation. At this point you can change the graph and equation by either entering new points and pressing the "Enter" button or use the coefficient scroll bars to change the values. If the coefficient scroll bars are used then the graph will be changed simultaneously with the equation.
