GeoGebra
You can use GeoGebra’s built-in tools to plot trigonometric functions. You can plot
-
sin(x)(sine) -
asin(x)(the inverse function of sine) -
cos(x)(cosine) -
acos(x)(the inverse function of cosine) -
tan(x)(tangent) -
atan(x)(the inverse function of contangent)
GeoGebra Instruction 1
Plot a Trigonometric Function
- 1.
- Open
Algebra ViewandGraphics ViewunderViewinMenu. - 2.
- As an example, let’s plot . In an empty row in
Algebra View, typef = sin(x)
and press
Enter. The graph then appears inGraphics View.
You can also modify the expression the way you’re used to doing, such as by adding an equilibrium .
Example 1
Plot the function
for in GeoGebra
In an empty row in GeoGebra, type
f = Function
and choose
Function(<Function>, <Start x-Value>, <End x-Value>)
from the suggestions that pop up. Replace the content of each field:
-
<Function>is replaced with2*sin(2x+pi)+5 -
<Start x-Value>is replaced with0 -
<End x-Value>is replaced with2*pi
Press Enter. The plot will appear in Graphics View.
