Error Dimension mismatch on ti89
Error Dimension Mismatch:
Two or more arguments must be of the same dimension. For
example, [1,2]+[1,2,3] is a dimension mismatch because the
matrices contain a different number of elements.

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 :-)

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.

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.
