Question about Texas Instruments TI-84 Plus Silver Edition Graphic Calculator

I can hardly read it if I put it on an angle.

One possible solution is to dim the screen contrast. To do this, turn the calculator on press the 2nd key, then the up arrow. If contrast has been darkened, this should work. To darken the screen if you get it too light, you do the same, but use the down arrow. Hope this helps.

SOURCE: my ti 84 screen is

Turn the calculator on. Press and release the [2ND] key, then press and hold the down-arrow key to lighten the screen. If you go too far, use the [2ND] and up-arrow keys to darken the screen.

You can add angle measures by hitting 2nd angle and choosing the degree option. Put this after a value (e.g. 90(degrees symbol)) and add you can add angles that way. Be sure that you are in degree mode when doing this (you can use the radian symbol for adding radians too). Still, this is a very tedious process and I recommend just adding angles as regular values (e.g. 90 + 200 = 290) and correcting for degrees manually.

There are two possibilities:

1) Your screen may have been physically damaged. This is not repairable.

2) The second possibility is the screen contrast is turned too high. You can adjust the screen contrast by pressing either 2nd and then the up and down keys or Alpha and the up and down keys, depending on your model. You will need to do this repeatedly to notice a change.

That is simple. It is a function like any other.

Press the key marked [SIN]

Screen displays sin(

Enter the value of the angle (make sure the current angle unit is the appropriate one).

Close the right parenthesis and press [ENTER]

Press the [MODE] key to access the mode comfiguration screen .

Set angle unit to to radian (see above)

Enter angle value in Decimal degrees only, use the [2nd][ANGLE] key sequence to have access to the degree symbol. The degree symbol must imperatively appear at the end of the angle value.

Here are some examples

If you use angle values in DMS, it will not be converted to radians, but to decimal degrees.

If you omit the degree symbol there is no conversion.

A general formula is Pi radians =180 degrees

On this family of calculators, you do as follows

To convert this back to DMS, press [ANGLE][|=>DMS][ENTER] and the calculator displays the original value 15 deg 25' 32"

- Enter the first number (degrees), ex:15
- Press [2nd][APPS] (ANGLE) to access the Angle functions
- Select [1: degree symbol] [ENTER]
- Main screen shows 15 deg
- Enter the minutes, ex 25
- Press [2nd] [APPS](ANGLE) to access Angle functions
- Select [2:' apostrophe] [ENTER]
- Screen echoes 15 deg 25'
- Enter the seconds number, ex 32
- Press [ALPHA][+] (") to access the double quotation mark.
- Screen echoes 15 deg 25' 32"
- Press [ENTER]
- Calculator converts this in decimal degrees 15.42555556

Hello,

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.

make sure that your mode is in degree, not radian. YOu can change it by simply press mode and move down to the degree selection and press enter.

press 2nd and then the down arrow over and over until the contrast is adjusted. Did you read the manual?
