HP Prime Graphing NW280AAABA manual CAS calculations

The menu buttons in CAS view are:

•: assigns an object to a variable

•: applies common simplification rules to reduce an expression to its simplest form. For example, simplify(ea + LN(b*ec)) yields b * EXP(a)* EXP(c).

•: copies a selected entry in history to the entry line

•: displays the selected entry in full-screen mode, with horizontal and vertical scrolling enabled. The entry is also presented in textbook format.

CAS calculations

With one exception, you perform calculations in CAS view just as you do in Home view. (The exception is that there is no RPN entry mode in CAS view, just algebraic and textbook modes). All the operator and function keys work in the same way in CAS view as Home view (although all the alpha characters are lowercase rather than uppercase). But the primary difference is that the default display of answers is symbolic rather than numeric.

You can also use the template key (F) to help you insert the framework for common calculations (and for vectors and matrices). This is explained in detail in “Math template” on page 24.

The most commonly used CAS functions are available from the CAS menu, one of the Toolbox menus. To display the menu, press D. (If the CAS menu is not open by default, tap .) Other CAS

commands are available from the Catlg menu (another of the Toolbox menus).

To choose a function, select a category and then a command.
