Problem for Texas Instruments TI-89 Calculator
TI-89 Problems
When i go to do a cos, tan, sin function or add an exponent (ie. 2^2) the calculator wont answer me. It just repeats what i have typed into it on the main screen without actually doing the tan function or squaring the number. Please help me. Is there something i need to change in the settings? Basically it just wont solve things and repeats what i have typed in right back to me. Basic functions like plus and minus work but that is about it.

There isn't anything "wrong" with it.
Go to mode, and set the results of your inquiries from Exact to approx.
If you put in cos(e^2), it will print out cos(e^2) because it's the most exact it can be without going into a decimal. (cos(e^2) will be a transcendental number like Pi).
