I try to use mathematica 5.0 to get the value of the function. The problem is : I can Plot the function get the graphic but when I run "Table" it to get the value it just told me that out of memory. If program can plot the function, it means that the program must get the value. But how could I get the value? Is there any way that I can get the value from the graphic I plot? Thanks for your great help.
