Description
The intensity of the color is related to the value of the function at any point.
Examples:
- x^2+y^2-9 (an equation of a circle with a radius of 3)
- sin(x)+cos(y)
- 2x−3y
- cos(x^2)-y
- (x−3)(x+3)-y^2
- y-x^2
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.
