To graph a 3D surface, start the equation with "z=".
To graph a 2D curve, start the equation with "y=".
Use "y" instead of "f(x)".
Try "y = x".
Can only graph two curves at once.
Graphs starting with "y=" can only have x and n to the right of =.
Can not graph equations with ?'s.
Try using < in place of = and look at the boundary.
Now graphing two functions of x.
That text cannot be edited.
Click the Zoom Out button to see more of the graph.
To graph a function, put it in the form y=... or z=...
Can only graph functions of x, y, r, theta, and n.
Now graphing z as a function of x, y, r and theta.
Now graphing z as a function of r and theta.
Now graphing z as a function of x and y.
Now graphing y as a function of x.
To exit the fraction, press the right arrow.
To exit the exponent, press the right arrow.
