Objective: To explore the effects of a and b in the graph f(x) = a sin(x) + b.
|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?|
