Description :: All Functions
Enter an Equation using the variables x and/or y and an =, press Go:
Description
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'
It has not been well tested, so have fun with it, but don't trust it.
If it gives you problems, let me know.
Note: it may take a few seconds to finish, because it has to do lots of calculations.
If you just want to graph a function in 'y=...' style you may prefer Function Grapher and Calculator
Zooming
Use the zoom slider (to the left zooms in, to the 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.

Sketch is a literary journal edited and published by Iowa State University students, that encourages all Iowa State students, regardless of year or major to submit works of artistic expression, written or visual. The journal began in 1934, featuring juried works by student writers and artists, and continues to the present, with one to three issues produced each academic year. Noteworthy Iowans, Ted Kooser, former United States Poet Laureate, and Tom Harkin, United States Senator from Iowa, have each had works published in Sketch during their undergraduate years.
This collection was digitized from archival materials held by Iowa State University Library Special Collections.
