How do you square on a ti 89 titanium
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 :-)

I tried to upgrade the OS from 1.07 to 2.09 on my
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.

How do you change the interval for a arc cos
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.

Prime
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).

Integration
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)

My ti 89 won't factor
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.
