To use the graphing program it is best to be in Quick Basic.
You must enter your function in the form {Y=sin(X)}
the letters in capitals must appear, i.e. the two variables must be x and y.
The function needs to be typed into line 80 using x and y, and into lines 6015
and 6115 using xc and yc.
While the program is running the following commands are available:
W.........................window size
Q.........................quadrants to be displayed
X.........................stretch the x-axis
Y.........................stretch the y-axis
S.........................step size (how solid the graphed line is)
J.........................how far the cursor moves
M.........................change the xmin and xmax values
».........................cursor right (increase x)
«.........................cursor left (decrease x)
end.......................quit
