Equation Grapher
Description
Enter an Equation using the variables x and/or y and an =, press Go
It can plot an equation where x and y are related somehow (not just y=...), like these:
Examples:
- x^2+y^2=9 (an equation of a circle with a radius of 3)
- sin(x)+cos(y)=0.5
- 2x−3y=1
- cos(x^2)=y
- (x−3)(x+3)=y^2
- y=x^2
If you don't include an equals sign, it will assume you mean "=0"
If you just want to graph a "y=..." style function you may prefer Function Grapher.
And feel free to contact me.
Note: it may take a few seconds to finish, because it has to do lots of calculations.
Zooming
Use the zoom slider (left zooms in, right zooms out).
To reset the zoom to the original bounds click on the Reset button.
Dragging
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.
