Here is an asurd example of a piecewise function

Y1=11 for X less than 10

Y1=3 for X in the range [10, 20[

Y1=X+5 for X in the range [20, 30[

Y1=10 for X larger than 30

Here is the screen capture of the Y= editor window.

You have

- the definition of the function within a domain, enclosed in () followed by the domain enclosed in ()
- a + to introduce the second piece (definition) (domain)
- + a third piece (definition ) (domain)
- and so on.
- Use the [2nd][TEST] key sequence to access the relational operators, less than, greater than, etc.

The arccosine function is defined for arguments in the range -1 to +1. -125.85/-120.36 is larger than 1 and hence outside the domain of the arccosine function.

To get the inverse trigonometric functions press the 2nd key then the trig function key. If you'll look at the key legends above the SIN, COS, and TAN keys you'll see the standard math notations for their inverse function.

1. To graph a function, Press [Y=] to enter the function editor.

2. Type in a legitimate function.

3. Press ENTER to validate the function.

4. Press the GRAPH key to draw the graph.

5. Play with the window dimensions or use the ZOOM feature

to see more of the graph (or less).

Try your settings by drawing the function y= x

If you have problem with Invalid Dimension or other errors, turn the

Statistical Plots OFF.

To do so, press [SHIFT] [Y=] to open the Stat Plots.

Type in the number to the left of the Option PlotsOff. Then press ENTER.

On these units, the "equals" sign ([=]) is located in the [TEST] menu. This menu is a [2nd] function of the [MATH] key.

This function is used to test if two expressions are equals. To evaluate an expression, simply hit [ENTER].

Good luck.

Hello,

You can actually represent all pieces of the function as a single function. There is an exemple in the calculator manual at page 17-4. You can use it to learn how to implement your function.

The relational operators (less than or equal to, etc.) are accessed through the TEST menu.

hope it helps.

type 15 then click a button that looks like this^. then 365. Then hit enter. it is like a normal clcutor except with more function. Sometimes you need to use the 2nd and the alpha button to do some functions.

The greatest integer function (also called a step function) is actually a piecewise defined function with a special definition. The function has the notation f(x)=||x|| or f(x)=[[x]] when it is written, but the TI-83 and the TI-84 designate this function by using f(x)=int(x) and is found in the MATH NUM menu. This function is the greatest integer less than or equal to x. So, f(1)=1 and f(1.4)=1. Since this is a piece-wise function you should use DOT mode.
