How do I enter this into Wolfram Mathematica? I have been working on this for three days and I cannot figure it out There is nothing helpful on google and the tutorial reading told me nothing. I DO NOT need the problems solved. I need the syntax to enter into wolfram mathematica to make it not give me an error message.
