Using a Program to Guess the Coefficients

Setting Up the Program
This program graphs the function A sin(BX) with random integer coefficients between 1 and 10.
Try to guess the coefficients and graph your guess as C sin(DX). The program continues until your
guess is correct.
: This program changes the graph window and graph styles. After you run the program, you
Note
can change individual settings as needed or you can press y L
settings.
Programs typically do not restore your settings in MODE, Y=, WINDOW and other locations that
were used by the program. This is dependent on who created the program.
