Question about Casio FX-9750GPlus Calculator
I can't get my calculator to graph anything. The only thing that it will do is draw straight lines no matter what I put in for the y equation. I have set the v window at 10 and it still doesn't solve anything. What are the solutions??
This calculator has so many options you can change, that it is possible one of them has been altered. Try pressing the master reset button at the back to re-set the calculator. Note that you will lose all your programs and data, so first copy out anything important. Also, set the xmin and xmax parameters to a higher value. To plot a sign wave, try xmin=-720, xmax=720, step=1, ymin=-1, ymax=1, step=.1 The step value won't change the appearance of the graph, just make it more chunky or fine. Use the equation y=sin x. This should draw a sign wave showing 4 complete waves. PS when you enter the X in the equations, you are pressing the X,0,T button, the one under the alpha key, aren't you? If you enter X using the x alpha key, it won't work. Also, to plot y=, make sure you change the func type parameter in the Set Up menu to y=. Hope this helps.
