2.2 Pretty Print/ 2DOther calculators like the TI-89 use a feature called pretty print to displayfractions, exponents, radials and other complex mathe

2.3 Drag and DropThe calculator has a drag and drop feature embedded in its software. Thisis helpful when the user would like to repeat a specific expr

dragging the stylus to an empty dialog box. Once at the desired location liftthe stylus from the screen to complete the drop. Try this again using the

Example 1. Try to simplify the expression√50. The expression√50 sim-plifies to 5√2. Your understanding of this simplification will depend on yourcurrent

3.1.2 ExpandTo access the expand command choose Action then Transformation andthen choose expand. If I want to FOIL the expression (x + 1)(x + 3), I c

Since the calculator is programmed to work with function notation like f(x)the calculator requires a multiplication sign between two variables to dis-

Example 4. We can also factor expressions such as 2x + 2 to 2(x + 1)using greatest common factor. Notice that prime polynomials are displayedthe same

Example 5. A basic example would be to solve for x such that x + 1 = 5.When using the solve command you must specify the unknown variable. Inthis case

Try solving the following equations and observe the reported solution.a) x2= 25b) x2= −25c) x2= 3In the previous examples the calculator reports multi

The variables seen as x, y, z, t are known as global variables which arereferenced in other areas of the calculator. If you store the value of x asa c

You can check the value of a variable by typing in the variable x andE. If cleared correctly, the variable will no longer output a constant value.Form

5.4 Finding intercepts and intersections5.4.1 y-intercept and traceWe can use the calculator to approximate x and y intercepts. We begin withthe funct

Confirm by tapping ok. The coordinate pair of the y-intercept is (0,1). Thetrace feature may be used to evaluate the function for any specified value of

The root is reported as the coordinate pair (−0.5, 0). Finding multiple rootsfollows the same process as explained above with a simple toggle betweenr

To find the first root, we repeat the process for root as we completed pre-viously. Our first root is provided as approximately (−3.162277, 0). If wesolv

You will notice that you have options labeled Max, Min, fMax, fMin.Using Max or Min finds the global maximum or the global maximum forthe given functio

If a global maximum or global minimum does not exist for the given function,an error message will be displayed.5.4.4 Finding intersection between two
