You can use it directly on tMin tMax the graph. Chapter 14 describes fStat Each user-created list name is added to the xStat , and yStat names, including Creating, Storing, and Displaying Lists Entering a List Directly in an Expression To enter a list directly, the syntax is: Enter any part of the expression that precedes the list.

For example, , and ABC Abc abc are three different list names. If at least one list element is a complex number, all elements in the list are displayed as complex. The affect the list editor.

Deleting Elements from a List To delete a single element from a list, move the cursor onto the element and press 3. The element is deleted. Page Using List Operations You can remove all user-created lists from the list editor and restore list names Reset all memory Chapter Resetting defaults does not affect the list editor. Page Chapter Lists min For a complex list, returns the smallest or max largest magnitude modulus.

The function must be valid for every element in the list; however, when graphing, undefined points do not result in an error. Page Attaching A Formula To A List Name Chapter Lists Attaching a Formula to a List Name You cannot edit an element You can attach a formula to a list name so that the formula generates a list that is stored of a list created from an and dynamically updated in the list name.

The example below builds on the example above for attaching a formula to a list. Notice that the formula in step 1 below is not attached to Generate a regular list by storing the expression Page Using The List Editor With Attached-Formula Lists When you edit or enter elements of a displayed list in any of the three current list editor columns while an attached-formula list also is displayed, the TI takes slightly longer to execute the edit or entry.

To reduce this effect, move lists with formulas off the current three- column display, either by scrolling columns to the left or right or by rearranging the list editor. Page Handling Errors Related To Attached Formulas You can successfully attach to a list a formula that does not yet resolve to a list. For example, you can attach However, if you attempt to display When you attach such a formula to a list name in the list editor, the formula is successfully attached, but an error occurs.

Page Detaching A Formula From A List Name As described above, one way to detach a formula from a list name is to edit an element of the attached-formula list. The TI protects against inadvertently detaching the formula from the list name when you move the cursor onto one of the elements.

On the TI, you can store up to elements to a vector in rectangular form. You can use two- or three-element vectors to define magnitude and direction in a two- or three- dimensional space. Enter each vector element value at each vector element prompt. You can select a vector conversion menu to override the mode setting page Chapter Vectors Editing Vector Dimension and Elements You can use : , 3 , and - p to edit matrix elements.
