Topic: Animating . . .

I want to show the graph of  sin(x) + cos(y) + k = 0  for values of k between -1 and 1.
How do you define k in the Custom Functions\Constants menu ?

Thanks in advance smile

Re: Animating . . .

You just enter k in a field in the Names column and a default value, which could b 0, in the Definition column.

The help might give you an idea:

You may also want to try the Animation.grf file installed with Graph in the Examples folder.
