No  Tools  Instructions 
1  Open GeoGebra and use the View menu to display the coordinate axes.  
2  Select the Slider tool and click on the Graphics view to display the Slider dialog box.  
3  In the slider dialog box, select Number from the option buttons, and leave the other options as is. GeoGebra will automatically givea as the slider name. 

4  Now create slider b similar to slider a.  
5  Type f(x) = a*sin (x) + b in the input bar and press the ENTER key to graph it.  
6  Move the small circles on both sliders. What do you observe?
