DescriptionIt can plot an equation where x and y are related somehow (not just y=...), like these:
- x^2+y^2=9 (an equation of a circle with a radius of 3)
If you don't include an equals sign, it will assume you mean "=0"
It has not been well tested, so have fun with it, but don't trust it.
Note: it may take a few seconds to finish, because it has to do lots of calculations.
Use the zoom slider (to the left zooms in, to the rigth zooms out).
To reset the zoom to the original bounds click on the Reset button.
Click-and-drag to move the graph around. If you just click-and-release (without dragging), then the spot you clicked on will be the new center
Note: the plots use computer calculations. Round-off can cause errors or values can be missed completely.
