You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

Milligram is a unit of mass. Milliliter is a unit of volume. Comparing the two is like trying to compare pounds and gallons. One ml of water will weigh 1000 mg. One ml of gold will weigh nearly 20000 mg.

Gram is a unit of mass (or weight). Teaspoon is a unit of volume. One teaspoon of water will weigh about 4.9 grams. One teaspoon of gold will weigh over 90 grams.

Use the (-) key just below the 3 key.

V = (pi)(r square)(h) V= Volume (the amount we need to calculate) pi = 3.14... r = radius of cylinder (remember this is half that of the circumference) h = height of cylinder To make it easier for you below are the figures for the Cylinder. Radius= 11.5 inches Height = 17 inches. Now use the formula above to calculate it. For the Jelly Bean its, Radius = 0.25 inches Height = 0.5 Use the same formula above for jelly bean as well. Once you have both figures, divide Volume of Jar by Volume of Jelly e.g. VolumeofJar/VolumeofJelly AND VOILA, you have the amount of jelly beans in a jar (Round the figure out) Cheers!

Press 2ND [TEST] 1. TEST is the shifted function of the MATH key.

Press the MODE button, press down-arrow to get to the second line, use left/right arrows to highlight the desired number of digits, press ENTER, then press 2ND QUIT.

The function of that button depends on the current graph mode. It will give you the "n" only in the SEQ mode. Press MODE, cursor down to the "FUNC PAR POL SEQ" line, highlight "SEQ", press ENTER 2ND QUIT. Now pressing that button will give you the "n".

Press LOG 3 ENTER

Press LOG 3 ENTER. The LOG key on the keyboard gives you base-10 (common) logs while the LN key gives you base-e (natural) logs. If you want the log to another base you can use the logBASE function found in the catalog.

The ERR:INVALID DIM 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. • You specified a list dimension as something other than an integer between 1 and 999. • You specified a matrix dimension as something other than an integer between 1 and 99. • You attempted to invert a matrix that is not square.

In order to select additional graphs, the Transformation Graphing Application will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the Application does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the Application. • Press [APPS] key • Select Transfrm from the menu • Press 1:Uninstall See cap images below

The TI-84 is a bit of a pain this way. You need to access the logBASE function either through the catalog or the MATH menu. You can't spell the function name as with some other calculators. Press MATH, scroll down to the logBASE entry, then press ENTER. This will put "logBASE(" into the entry line. You can then enter the arguments and press ENTER to calculate the result. For example, to calculate the log base 2 of 8, press MATH, down-arrow a number of times to logBASE, press ENTER 8 , 2 ENTER. This should give you 3.

I am just going to be frank here, you have to do the math. Move the decimal over a couple spaces and you will be fine. You can post back if you need to know how to convert it. Th ti-84 can't do everything. You need the ti 89 to do more advance things, which I don't think you need.

Press 2ND [TEST] 3. TEST is on the MATH key, two keys down from the 2ND key.

Press the Mode button/key. Scroll down to the line Stat Wizards and highlight ON. Press ENTER. to validate the choice. Exit the Mode setting. Now Press the key sequence [2nd][VARS] (DISTR) to access the distributions. Scroll to find your distribution, select and press ENTER. You will have your entry screen.

What's the determinant of the numbers in matrix A? A singular matrix is a matrix whose determinant is zero.

Your calculator may or may not have a program for unit conversion, but the best method is to understand the metric system so you can do these conversions without a calculator. A meter is the same as 100 centimeters, so divide 11390 by 100 to get 113.90 m^3.

Rather than relying on a calculator, I highly recommend taking the time to practice metric conversions. It is very common for high school and even college professors to try and trick you by, for example, requesting the answer in centimeters when the question is in meters.

To graph a sequence, you must set the Graph Mode to Seq. On line Func, use the right arrow to highlight Seq. this way when you press the key X, T, Theta, n you enter the variable n Make sure you turn off the StatPlots. Press [2nd][Y] (StatPlot), then select [4:PlotsOff]. See the screen capture.
