Have you tried 2nd then down arrow. This adjusts the brightness of the screen. You may need to repeat it a few times (you must release the 2nd key, you cannot just hold it down and type the down arrow many times).

That means that you know your calc crashed. This can be caused by taking out the batteries durring running time, happened just randomly. Well nothing to fear just press clear and it should go away but if it stays on that screen you have problems and is best to try some of these methods. Take out all the bateries and press and hold the on button for 30 seconds. Put the batteries back in and it should have reset. Warning you should archive everything incase this happens. To archive go to 2nd mem and hit enter to put a astrick next to the app (meaning archived)

SOURCE: How do I calculate the ArcCos of say -.25?

There is nothing wrong. Your angle unit is set to radians and the calculator gave you the correct angle the cosine of which is -0.25: the answer is in the same unit as the one your calculator is configured for.
Press [MODE]. Use arrow to scroll to 3rd line, highlight Degree and press [ENTER]. Press [2nd][QUIT] to return to main calculator screen.
As long as the angle unit is set to degree, the angles calculated by the inverse trigonometric function will be in degrees.

Hope it helps.

My Ti-84 plus silver is giving me wrong answer when I use normalcdf. I used video guide to make sure my entries were correct. lower:280 upper: 1E99 mu:272 sigma:9 I get answer .81296 the video and correct...

That is what I get with your numbers on the TI84 Plus Silver Edition 0.1870313608. I get the same on the TI83 Plus. What can I say?. Apart from an error entering the numbers ( a 6 for a 9, a 3 for an 8) I cannot think of anything else. Sorry.

Why can't i see the plotted points when i try to graph my L1 in a scatter-plot?

You cannot have a scatter plot with just one variable. You need values in L1 and values in L2. If you have only one set of values you can do 1-var statistics and plot a histogram (x-value vs. frequency).

TI-84 plus silver edition. Syntax error on problems such as 8(-)5. How do I get rid of it?

If you want to subtract 5 from 8, enter it as 8 - 5.

The - key to the right of the 6 key is for subtraction, the (-) key to the right of the decimal point key is for entering negative values.

Hello where is the fraction button on the ti-84 plus silver edition

There isn't one. If you want to convert a value from decimal to fraction, use the >Frac function (press MATH 1). If you want to enter a fraction, simply enter the numerator, divide, then the denominator.

For example, to calculate 1/4 + 1/3, press
( 1 / 4 ) + ( 1 / 3 ) MATH 1 ENTER
and you'll see 7/12.
