The TI-83 Plus and TI-84 Plus offer a diversity of different settings for customizing calculations and the fashion graphs are displayed. While some of these options are more artful, similar setting the graph to be displayed in a dissever screen or numbers to exist displayed with ii decimals for doing calculations with money, not having some settings configured correctly can lead to making errors in your calculations. This tutorial explains the diverse brandish style settings available on the TI-83 Plus and TI-84 Plus, which can be reached past pressing MODE.

Settings Menus on the TI-83 Plus and TI-84 Plus, respectively

You tin can select various settings by using the pointer buttons. To choose a selected pick, press ENTER.

NORMAL / SCI / ENG

NORMAL is the default setting and displays numbers every bit decimals until they are at least eleven digits long, at which point it reverts to scientific notation.

SCI displays all numbers in scientific annotation, e.g. 1.0057E4

ENG displays numbers in scientific annotation with powers of g instead of powers of 10, which ways that 10 would be displayed as 10E0, whereas 10000 would be displayed equally 10E3.

Float / 0 / 1 / ii / iii / iv / 5 / half-dozen / 7 / 8 / ix

This setting determines how many decimal places the calculator shows when computing answers. FLOAT denotes the maximum number of decimal places available. If we selected 2 for example, x.4345 would be displayed every bit x.43.

RADIAN / Caste

This setting determines how angles are interpreted for trigonometric functions. If yous need to switch betwixt radians and degrees on your TI-83 or TI-84, this is the place to toggle this setting. For example, if we desire to evaluate the sin of 90 degrees, In RADIAN mode, we would enter sin(pi/two), which would requite united states of america the right reply of 1, whereas in DEGREE mode, we must reply sin(ninety). Entering sin(90) in RADIAN mode or sin(pi/2) in caste fashion will not give the intended result, and so information technology is very important to know which mode y'all are in. These settings also make up one's mind how trigonometric functions are graphed.


FUNC / PAR / POL / SEQ

These settings announce the current graphing fashion.

FUNC (function) plots functions in rectangular coordinates with Y as a role of X.

PAR (parametric) plots functions in rectangular coordinates where 10 and Y depend on a third variable, T.

Politician (polar) plots functions in polar coordinates, where R (radius) is a function of theta (angle).

SEQ (sequence) can exist used to plot sequences.

CONNECTED / DOT

This option toggles how graphs are displayed. The TI-83 Plus and TI-84 Plus graph functions just equally a educatee might by manus, by looking at the value of a part at many different points and then connecting the dots. Continued is the default style and connects a line between points graphed on the calculator. DOT plots only specific points depending on what your estimator is set to choose. Typically Connected is more than useful, simply in specific instances DOT can be helpful in solving problems.

SEQUENTIAL / SIMUL

This setting determines the order in which functions are graphed. SEQUENTIAL graphs functions one at a time. For example, in function graphing manner, your calculator volition graph Y1, then Y2, and so forth. SIMUL (simultaneous) graphs all functions at the aforementioned time.

Real / a+bi / re^θi

These settings determine the mode in which complex numbers (those involving the foursquare root of a negative number, or i) are handled. In REAL mode, whatever answer involving the square root of a negative number will effect in an mistake. In a+bi style, results are displayed as a real part (a) plus an imaginary function (b) times i, the imaginary unit. In re^θi mode, circuitous numbers are displayed in polar form, which may be more than useful for calculations and is commonly used in engineering science and physics.

Full / HORIZ / G-T

These settings determine how the graph screen is displayed. FULL is the default setting and lets the graph have up the entire screen. In HORIZ (horizontal) mode, the screen is split up horizontally so that the graph occupies the upper half, whereas the residue of the screen tin be used to enter equations or perform calculations. In G-T (graph-tabular array) way, the screen is carve up vertically so that the graph occupies the left half, and the respective table of values occupies the right one-half.
