Using the normalcdf function on the TI-84. These instructions will work for the TI-83 and TI-84 families of calculators. Read the problem carefully: Consider the weights of 18 month old boys in the U.S. According to published growth charts, the average weight is approximately 11.8

Look it up. Here is one approximation from the classic “Approximations for Digital Computers” by Hastings, published in 1954. x = (1/\sqrt{2\pi}) ...

When the TI‑84 Plus CE detects an error, it returns an error message as a menu ... A function or instruction does not have the correct number of arguments.

Description. Complementary error function. ERFC(x) returns the error function integrated between x and infinity.

Gaussian Error Function: erf( and erfc( Description A set of programs the computes the erf(x) and erfc(x). Unlike similar programs available here, the result given by these programs is accurate to all 10 decimals displayed by the calculator.

Calculates the error function erf(x) and complementary error function erfc(x).

Apr 15, 2021 · The TI‑84 Plus CE allows for undefined values on a graph. The ERR:INVALID DIMENSION error message may occur if you are trying to graph a function that does not involve the stat plot features. The error can be corrected by turning off the stat plots. To turn the stat plots off, press y , and then select 4:PlotsOff.

15.04.2021 · Why does my TI 84 keeps saying error syntax when graphing? The TI‑84 Plus CE allows for undefined values on a graph. The ERR:INVALID DIMENSION error message may occur if you are trying to graph a function that does not involve the stat plot features. The error can be corrected by turning off the stat plots.

The TI‑84 Plus CE allows for undefined values on a graph. The increment in a For ( loop is 0. INVALID You attempted to reference a variable or use a function where it is not valid. For example, Yn cannot reference Y, Xmin, @X, or TblStart. In Seq mode, you attempted to graph a phase plot without defining both equations of the phase plot.

Version 1.0. December 14, 2011. Welcome to the first version of Calcblog’s complete TI-83 Plus and TI-84 Plus graphing calculator function appendix. You can use the index below to scroll down to the function you want to learn more about. Of course, not all information is necessarily correct, and there are probably errors since this is the ...

To resolve this error, try zooming in as close as possible to the location of the zero while still being able to separate the function from the axis line. To zoom in, please do the following: • Press [ZOOM] [2]. • Using the arrows keys, scroll as close as possible to the zero of the function. • Press [ENTER]. • Repeat as necessary.

The command contains a syntax error. Look for misplaced functions, arguments, parentheses, or commas. For example, stdDev(list [, freqlist]) is a function of the TI‑84 Plus CE. The arguments are shown in italics. The arguments in brackets are optional and you need not type them. You must also be sure to separate multiple arguments with a comma (,).
