Examples

1. You are asked to define a function that computes this error approximation formula.

   Valid names for the function are e, E, formula, computation, value, my_function, fun, etc. But, none of these are good names for this function. It is important to choose a name that is descriptive and will help you remember what the function does. Thus, a better names for this function would be errorApproximationFunction, errorApproximation, error_approximation, Error_Approximation or even just errApprox.

   Consistent capitalization is also necessary to make it easier to remember how to call your functions.
