Formulae can enable you to make mathematical statements for the whole set of values of the arguments (the domain) at the same time instead of repeating the statement for each value.
A piecewise defined function is a function which is defined symbolically using two or more formulas
Differential Calculus is to take the derivative of the function. It is important as it can be applied and supports other branches of science. For ex, If you have a velocity function, you can get its acceleration function by taking its derivative, same relationship as well with area and volume formulas.
Your age is a linear function (of time).
There are different types of speed formulas: Speed= Wavelength(frequency) or Speed= Distance/Time
To measure time
In the Casio Scientific Calculator, it is possible to program in favorite formulas. The instruction manual has a step by step explanation. In short, a soft key can be accessed through function save. After inputting the formula, again go to function, select a letter for identification, and then save to retain the formula.
Yes. The whole idea of an electronic spreadsheet is to be able to do things automatically by having formulas to work out calculations rather than you doing them manually.
When saving document for the first time functions save and save as behave alike. If the document has been saved then: Save - you save the document as it is. Cannot change its location, name or format/extension. Save as - this function allows you to change all above metioned parameters of the file.
The function library tab.
Functions are pre-written formulas. Functions differ from regular formulas in that you supply the value but not the operators,such as (+,-,*,/). You can use the SUM function to add.

Templates can be changed, so yes you can add formulas and then save the template and have the new formulas included.

Yes. Just save as.
In MS Word, Save As is used to change the file name, format & location.'Save' & 'Save As' perform same job that is to save a document. However, the way they achieve this is slightly different. Save function saves the document using same file name, format and location. However, Save As function opens a dialogue box in which the user can change the name of document, format & location.Note: Save function also opens a dialog box when you try to save a new document.
