GRAPH A FUNCTION f OF TWO VARIABLES |
|
|
To graph a different function, edit the function expression. Just highlight the expression and type over it. Variables must be entered as Wildcard. To input the variable x as a Wildcard, first type Shift + ?, then type x; similarly, for y. When you place the cursor over the image, the cursor becomes a hand. As you drag the image, the graph changes orientation. If you "swipe" the cursor across the screen and release it, the graph will continue to rotate as an animation. To increase the number of points for higher resolution, click on the More Accuracy button (small grid icon below the rocket). To change the graphing window boundaries, edit the values: xMin, xMax, yMin, yMax, zMin, zMax. To reset the original values, or if an error occurs, reload the file.
