Topic: Independent Variable

Is it possible to change the independent variable (x) to another variable, say K?
If possible, how?

Re: Independent Variable

No, not directly. But if you think it is fun, you can create your function as a custom function, e.g. g(z)=sin(z)+z^2  and then plot f(x)=g(x). However you can change both the text shown in the legend and the label at the axes to use something else than x.
