So if you have maybe the function does something wacky like this on the right hand side. If it was even, you would reflect it there. But we want to have an odd function, so we're going to reflect it again. So the rest of the function is going to look like this. So what I've drawn in the non-dotted lines, this right here is an odd function. And you could even look at the definition.

Function evaluation is something that we’ll be doing a lot of in later sections and chapters so make sure that you can do it. You will find several later sections very difficult to understand and/or do the work in if you do not have a good grasp on how function evaluation works.

  • I know you said non-VBA preferred, but if you end up with no other solutions, the Range object has a HasFormula property. Returns: True if all cells in the range contain formulas; False if none of the cells in the range contains a formula; null otherwise.
  • Description. The Microsoft Excel ISNUMERIC function returns TRUE if the expression is a valid number. Otherwise, it returns FALSE. The ISNUMERIC function is a built-in function in Excel that is categorized as an Information Function.
  • Evaluate the function as s approaches zero and as s approaches infinity. That will give you a very quick look at low and high pass filters. Band pass can be a little trickier, and may require some factoring first to get it to a form that makes sense to apply the aforementioned process.
