Combining Functions

Functions can be combined to produce new ones. Simply enter the functions after the equals sign in an expression as if the functions were variables. For example, if you have defined functions f(x) and g(x), you can plot the sum of f and g with:


sum(x)=f(x)+g(x)

Note that you can only combine functions of the same type, e.g. an explicit function cannot be combined with a polar function.
