P+q / p = 2

Raise e to the first power. On the TI89, press diamond e^x 1 ) ENTER

26 acres is about 105,219 square meters.

Transfer it to the calculator, if you have not done so already. If it has been installed, it should show on the AppsDesktop. To explore the desktop, use the arrow keys. You can also deactivate the AppsDesktop ON on the last page of the MODE, to have a list displayed when you press the Apps key. Once you find the NoteFolio app, select it and press ENTER. Here is how you proceed afterwards.

diamond sin^-1 [value] ) ENTER For example, to calculate the arcsine of .5, press diamond sin^-1 . 5 ) ENTER

An argument is of the wrong data type

i2sqrt(2), where i is the square root of -1.

One way is to multiply the quantity by itself. Another is to raise it to the second power using ^ (just above the divide key). You can also take it's logarithm, double it, then take the antilog :-)

Sometimes you can just carry on as if no error message was seen and the OS downloader will upgrade the calculator anyway. I have had to use the old GraphLink software with the series gray cable to upgrade very old OS's. As a last resort, you may be able to delete the OS system entirely from the calculator (check on the Internet to see how to do that for your specific calculator) and use the TI Connect software with the silver USB cable to add the OS from scratch.

g(y) = 1-y

I'm not sure of the question, but to plot arccos set mode to: graph='function' and angle to 'degrees' (for example). Go to WINDOW and set xmin=-1, xmax=1, xscl=0.1, ymin=0, ymax=180, yscl=50, and xres=1. Press GRAPH. You will get a plot of arccos from -1 to 1.

You may simply apply the power rule for determining the first derivative. If y = a * x^b then y' = a * b * x^(b-1). In your case, a = 1, b = -1 you get: y = x^(-1) => y' = 1 * (-1) * x^(-1 - 1) = -x^(-2).

The integral cannot be calculated in terms of the elementary functions. It is given by dilogarithm Li_2. Note here that log stands for the natural logarithm (ln)

The polynomial cannot be factored in the set of Real numbers: The roots of the polynomial equation are complex. You should use the command cFactor( found under F2:Algebra> A:Complex>2:cFactor( However, you should set the Mode Complex>Rectangular, and the EXACT/APPROXIMATE mode to Exact, otherwise your roots will be in decimal representation.

if u are typing and u got to the end of the page, or u want to go to anew line without getting to the end, just press the enter key or continue to press the space bar key, till the cursor move to the next line. try it!

The 2nd key is not supposed to register anything. It puts the calculator in a waiting state until you press a valid key.
