Grapher - Use radians mode instead of degree mode
I recently started using grapher. I am wondering how I can tell the program to show me the labels on the x-axis in terms of PI, instead of of numbers. I need to do this since I want to graph some stuff involving sin, cos and tan... (When I graph a sin function, the programm shows me that the line intersects the x-axis at more or less 3.14, which is PI, but how do I actually make it show me PI?)
Thanks already....
