CalcES supports multiple types of graphs, including Polar graphing. For example, you can graph a sine function in polar coordinates using the syntax Sin(t), where t is the angle.
Entering expression with t variable will treat as polar function.
Example
Example: 1−2Sin(t)
Remember change the angular unit to RAD
Enable “Polar coordinate” option in Settings to draw graphs on Polar coordinate
Set the polar start, stop and steps if needed. The default values is start=0, stop=2Pi, step=0.1
Enable Tangent
and Trace
options to display tangent of polar graph at a specific point
Enable TraceVar
option to display a slider, use this slider to change the value of the t variable
Tap Calc
button to show the calculation panel
Enter the value of t in the t=
field, and then tap Calculate
to calculate graph properties.
Tap Table
button to show the table panel, it displays the table of values.
The left column is t values, and the right colum is r(t) values
Using :
to separate between graphs.
Example
Example: 2−2Sin(t):3Cos(3t)
Tap GRAPH
