Display and compare the graphs of Sine, Cosine and Tangent
over the ranges: angle 0 to 360 degrees & amplitude +/- 1.5
Equation is of the form f(x) = A* XXX (Bx + C) + D
where XXX is the trigonometric function Sin, Cos or Tan
Parameters A,B,C & D can be changed in steps of 0.1 for
A,B & D; 10 for C using the arrows beside each
corresponding field, in which case the graph is changed
dynamically. Specific parameters can also be entered
directly into the corresponding field. in this case
the new values will be used as they are entered by
pressing RETURN or ENTER, or if return and enter are not
used, by clicking the 'Plot it' button.
The tick box beside Sine & Cosine is to allow these two
graphs to be displayed together. Note that the parameter
values are only applied to the trig function that has
been selected by the radio button.
Reset effectively returns the display to f(x) = XXX(x)
where XXX is the trig function Sin, Cos or Tan
