Folks, I just got Mathematica 3.0 for the Macintosh student version(2 plus months). I want to do something that should be available in this powerful program. I want to trace a 2D graph to recheck if my manual math was correct. Items such as intercept points and such. I got the users manual(thick book) and such but there is not much information other than manually tracing using the cmd-click on the graph to hopefully get the about right information(not). I also have a TI-85 which does this real fine. My Graphing Caluculator that was included with the Macintosh does real good(not exact). Here is the thing I want to know: I have a graph of sqrt[x], and abs[x] I want to know graphicly and by hard math what the intercept point are. I want to know the two point exactly where they intercept at. How do I do the math through mathemathica 3.0 and show graphicly where they are. If Mathemathica 3.0 does not do this please let me know. Note: I am not taking any math classes yet I will be in about a week. I am just rying to brush up on my math before I start up again. Please send information to my email address listed below Thanks in advance! Sincerely, Ivan G. Burch II aka enforcer at email address: "ivanb at hula.net"
