However, in Home view, it accepts X (uppercase x) as a variable. What I'm doing is to change from x to X manually. F0 through F9 are the global variables for functions to be plotted. You can use these within the CAS environment and define, for example, F1 to be a function to plot. In CAS view, functions take the form similar to: (x)>(x^2+2*x3). So you can do something like: F1:=x>x^24; Notice that the calculator will automatically convert to upper case and return: (X)>(X^24). Since the variables of functions are just placeholders, you could really use whatever variable you want. However, the system variables F0 through F9 only accept X as their placeholder variable (hence the autoconversion). Here's a short example of how you can use this in your calculations: g1:=x^34*x^2+2*x1; g2:=diff(g1,x); F1:=unapply(g2,x); In this example, diff() computes the derivative, and unapply() turns the expression (in this case, g2) into a function whose placeholder variable is 'x'. Since we are saving the result into F1, it will autoconvert for us. Graph 3D  QPI  SolveSys
