Underscores are commonly used in variable names in many programming environments. For example, Mathematica recognizes Sumas the symbol representing the sum function, but does not recognize sumas the sum function. Clear functions (downvalues): Copy to clipboard. If you're having problems with your program, it is sometimes a good idea to clear all the variables and then run it again, to make sure that in debugging it you didn't mess up the values of the variables.

Mathematica's inbuilt functions, (like Exp, Sin etc) are always capitalised. Curated computable knowledge powering Wolfram|Alpha. It emphasizes the Sturm-Liouville system and the generation and application of orthogonal functions, which are used by the separation of variables method to solve partial differential equations. Now, suppose I want to remove the value from a_1 so that when I next try to substitute into myf, the variable name a_1 is used and not the value of a_1.
