**TI-84 Plus CE: Version 5.3 Highlights**

**Piecewise Function**

The piecewise( function is added to the Math menu under the
math submenu, option B. As a result, the
equation solver has been moved to option C.
The piecewise function can hold from 1 to 5 pieces.

**Conditions Template**

Version 5.3 adds 16 test templates involving the variable X
to the Test menu ([2nd] [math]). This is
meant to compliment the new piecewise function, especially in function
graphing. However, the variable can be
changed as needed. The screen shot below
shows a condition template with a piecewise function.

Demo:

**Tangent Drawing Command Adds Option to Store Tangent line**

When a function is drawn, you can calculate and draw the
tangent line at any continuous point while you are on the graph screen. Version 5.3 adds the option to store the
Tangent line to any available graphing equation (Y# for example). The new functionality is available only in
the Function mode.

To generate the Tangent line, press [2nd] [prgm] (draw),
option 5 to call up the Tangent command.
Arrow to the desired point. Press
[graph/f5] (MENU) for options. Select your
options, then press [enter]. Use either
arrow keys or enter a number to get to a point and commence drawing the tangent
line.

A demonstration is shown below.

**Program Editing Tools**

It’s been a long time coming: the TI-84 Plus CE now has editing tools! We now can insert comments (comments are indicted
with quotation marks), insert blank lines, copy, cut, and paste lines. There is even an option to execute the
program immediately. It is all accessible
from pressing [alpha] [graph/f5].

**Running Archived Programs**

You can now run archived programs without unarchiving the
program into RAM first. We still need to
unarchive programs in order to edit them.

**Other**

* Running assembly
programs will no longer require the asm( command.

* The fraction bar can be called by [alpha] [X,T,θ,n].
