Functions are designed to perform a specific task or tasks repeatedly to avoid cluttering a worksheet with too many statements. We have already used many functions that come with the Mathcad software (e.g. ‘length’). Users can create their own functions that are accessed in the same way as the built in functions, as many as you need. For HW#3 you will create several simple functions. Function Structure The input list can contain as many variables and vectors as you want to pass into the function. These are to be generic variable names, not the same ones used in the worksheet. It can work both ways, but its good form to go generic. The names in the input list are the same ones to be used in the function. See the example functions in Lecture 4 (the for-loop section) and on the next page to see how this works. If I say FunctionName (x) := then x is the name inside the function being used to represent that information from the main worksheet.x is the name inside the function being used to represent that information from the main worksheet....
