Plot2D will plot cartesian, polar and parametric functions. Enter your function in the provided box and click the draw button to plot. Click the sample functions box to select and plot some common functions.
The cartesian function is the default function and is entered without identification;
for example: 2*x^2 + 3 or 2*sin(x) + (1/2)*cos(x) . Note; cartesian functions are written as a function of x.
To enter a polar function enter the function with a leading identifier;
for example: polar: sin(a/2) where -2∏ ≤ a ≤ 2∏ is the polar range. Note; the function is written as a function of a (not x).
To enter a parametric function enter the function with a leading identifier;
for example: para: x=t^2; y=sin(t) . Note; the x and y functions are written as a function of t.
When creating or entering your own functions you may use the following constants, operators or mathematical functions.
You may print the plot by performing a right mouse click on the area above the plot. From the displayed menu select Print. This will display a print dialog from which you can send the contents of the web page to your printer.
You can also try the Windows version of Plot2D. This version has many more features. For example, the Windows version allows you to save the functions you enter and call them back again for later use. There is no limit to the number of functions or libraries of functions you can save and recall for plotting.
