Question about Texas Instruments Office Equipment & Supplies

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

To switch the radix mark between the US and European modes, turn the calculator on, then press and release SHIFT, then press and release the decimal point key. You'll note that the shifted function of the key is marked "./," which should serve as a reminder that this functions switches between comma and dot.

Syntax is **$( function,lower bound,upper bound) =**

Press the Integral key. $(

Type in the function eg. sin

Type the variable: SHIFT ) to enter X

Type in a comma separator ,

Type in the lower bound of the integral

Type in a comma separator ,

Type in the upper bound

Close the right parenthesis )

Press = to get the result.

Note: You have to wait for the calculator to return with the answer. Some calculations may require time to perfor.

Don't look above the keys, but at the keys themselves. The comma is not a shifted function, but the primary function of the key located just above the 7 key.

Here is a picture of the keyboard. The comma is in the column of keys below the MODE button. In this column, the comma is between the sine function SIN and the key for the number 7. To its left is the square (x^2) key and to its right is the left parenthesis (.

Feb 26, 2010 - I was right to suggest to
you to read the page on domain and range of functions: it would have
clarified the concepts to you.

The domain of the sine function is from -infinity to + infinity. But since the function is periodic, with a period equal to 2Pi, by limiting the DOMAIN of values to -1*Pi to +1*PI you see all there is to see. All the rest can be obtained by translation of the curve.

The RANGE of the sine function is LIMITED to values in the interval [-1, 1]

Let us summarize: The DOMAIN of the sine function is ]-infinity, +infinity[ and its RANGE is [-1,+1].

That being said, there is something I would like to point to you

These are the numbers.

You want a "square", so be it. Here is the window setting

and the corresponding picture. Does it look like a square?

Why do you insitst on drawing a square? Horizontally you have the angle ( a number with a unit), while vertically you have a ratio of two lengths ( a pure number). Would even think about a square if you drew your sine function with the degree as angle unit. Horizontally you would have a domain [-180 degrees, 180 degrees] while vertically you have a range [-3.14..., +3.14...]. How can that be a square?

I showed you how you can fix every dimension in the graph window (see the first picture) . Choose any values that you believe will give you a square graph. And I do mean to say "that make you believe", because there is no meaning attached to the "fact" that the window looks like a square. An angle cannot be compared to a the projection of one side of a right triangle onto the hypotenuse.

Try reinstalling, might be memory got used up

Ti 83 and ti84 really have no difference and operate the same. There was something different or you had varibles used by multiple programs that conflicted w/ the ti84 and it would have done the same on the ti83. If you like to rework it and need help email me at raklein62@yahoo.com

Turn off transformers. Go to apps and go all the way down until you reach transformers then hit enter. Then a menu should appear and hit uninstall that should fix it.
