Evaluating algebraic expressions
When an expression is highlighted,
pressing ENTER will cause it to be
algebraically evaluated and any functions
to be applied accordingly. For example,
if you highlight (2x+3)^3 as shown right then
pressing ENTER will give the result shown.
Further examples are shown below. In each case it is only the highlighted
expression which is evaluated. Depending on the settings of CAS MODES
there may or may not be intermediate steps displayed between those shown.
Notice the lack of a ‘+c’ indefinite constant in the integration result. Here, this
is because we are using the definite integral (see page 81 and the page
following). A better alternative is to use the INTVX function as shown below,
even though it still does not add the ‘+c’. See the page after this for
information on using functions in the CAS.
Calculator Tip
The result of the 40! example above extends off the edge
of the screen and pressing will not scroll it. If you press
the VIEWS button, then you will find that it can now be
scrolled and the entire value seen - all 48 digits of it.
