Can anyone please tell me how to get a picture with labels in Greek letters such as "alpha", "beta", etc..? One other question: How to put arrows in Mathematica plotting? Say something like arrow from 0, 0 to 2,2 Thanks a lot! PS Is there a way that we can key in LateX form and get what we want in plotting? Michael
