The TI-83 Plus and also TI-84 Plus sell a range of various settings for tailoring calculations and also the method graphs room displayed. While some of these alternatives are much more aesthetic, like setup the graph to be presented in a split screen or numbers to be presented with 2 decimals for doing calculations v money, not having actually some settings configured correctly deserve to lead to making errors in her calculations. This tutorial explains the various screen mode settings available on the TI-83 Plus and TI-84 Plus, which deserve to be got to by pushing MODE.

Settings Menus ~ above the TI-83 Plus and TI-84 Plus, respectively


You can select various settings by utilizing the arrow buttons. To select a selected option, push ENTER.

NORMAL / SCI / ENG

NORMAL is the default setup and displays numbers as decimals until they are at least eleven number long, in ~ which point it reverts to scientific notation.

SCI display screens all number in scientific notation, e.g. 1.0057E4

ENG displays numbers in scientific notation with powers of 1000 rather of powers of 10, which way that 10 would be displayed as 10E0, whereas 10000 would certainly be shown as 10E3.

FLOAT / 0 / 1 / 2 / 3 / 4 / 5 / 6 / 7 / 8 / 9

This setup determines how many decimal locations the calculator shows when computer answers. Rise denotes the maximum variety of decimal places available. If we selected 2 for example, 10.4345 would certainly be shown as 10.43.

RADIAN / level

This setting determines just how angles are taken for trigonometric functions. If you have to switch in between radians and degrees on your TI-83 or TI-84, this is the location to toggle this setting. For example, if we want to evaluate the sin of 90 degrees, In RADIAN mode, us would go into sin(pi/2), which would offer us the correct answer that 1, conversely, in degree mode, we should answer sin(90). Start sin(90) in RADIAN setting or sin(pi/2) in level mode will not offer the plan result, so the is an extremely important to recognize which setting you room in. These settings additionally determine exactly how trigonometric features are graphed.


FUNC / PAR / POL / SEQ

These settings signify the current graphing mode.

FUNC (function) plots functions in rectangular coordinates with Y together a duty of X.

PAR (parametric) plots attributes in rectangular collaborates where X and Y depend on a third variable, T.

POL (polar) plots features in polar coordinates, wherein R (radius) is a function of theta (angle).

SEQ (sequence) can be supplied to plot sequences.

CONNECTED / DOT

This alternative toggles exactly how graphs space displayed. The TI-83 Plus and also TI-84 to add graph attributes just together a student might by hand, by looking at the worth of a duty at countless different points and also then connecting the dots. Linked is the default mode and also connects a line in between points graphed on the calculator. Period plots only details points depending upon what her calculator is collection to choose. Typically linked is much more useful, however in certain instances DOT can be helpful in addressing problems.

SEQUENTIAL / SIMUL

This setting determines the stimulate in which features are graphed. SEQUENTIAL graphs attributes one at a time. For example, in role graphing mode, her calculator will certainly graph Y1, then Y2, and so forth. SIMUL (simultaneous) graphs all functions at the very same time.

REAL / a+bi / re^θi

These settings determine the path in which complicated numbers (those including the square root of a an unfavorable number, or i) space handled. In actual mode, any answer entailing the square root of a an unfavorable number will an outcome in one error. In a+bi mode, results are presented as a real component (a) to add an imaginary part (b) time i, the imaginary unit. In re^θi mode, complex numbers are displayed in polar form, which may be more useful because that calculations and also is typically used in engineering and also physics.

FULL / HORIZ / G-T

These settings determine just how the graph screen is displayed. Full is the default setting and allows the graph take up the whole screen. In HORIZ (horizontal) mode, the screen is separation horizontally so that the graph occupies the upper half, conversely, the remainder of the display screen can be offered to get in equations or do calculations. In G-T (graph-table) mode, the display screen is separation vertically so that the graph occupies the left half, and also the equivalent table of worths occupies the ideal half.

We hope you have found this indict on configuring your graphing settings on the TI-83 Plus and TI-84 plus useful. Let us recognize what setups you prefer and also why, or leave a blog post if you have any additional questions!
