Type in a sine function with Greek parameters that can be changed by using sliders.[br][br]Explore the construction and learn how to visualize sine functions with [i]Graphing [/i]in [i][url=https://www.geogebra.org/calculator][i]GeoGebra Calculator Suite[/i][/url][/i]. Then try it yourself by following the instructions below.
[table][tr][td]1.[/td][td]Type [math]f(x)=sin(x)[/math] into the [i]Input Bar[/i]. The graph of [i]f(x)[/i] will automatically be displayed in the [i]Graphics View[/i].[br][b][/b][b]Note:[/b] Make sure that the chosen [i]Labeling[/i] option is [i]All New Objects [/i]so you can see the labels of the objects in the [i]Graphics View[/i]. You can set this in the [i]Settings [/i]by selecting [i]Global Settings[/i] on the right.[br][/td][/tr][tr][td]2.[/td][td]Type the letter [i]a[/i] into the [i]Input Bar[/i] and press [i]Enter[/i].
