You can not achieve this with the Ti-nspire cx. Only the CAS version will give the square root form. On the CAS there is an option in the settings called "EXACT" under calculation mode. The cx does not have this mode.

SOURCE: ti-89 titanium SIN!!!!!

The answer that you have received in actuality is correct. However, it is in exact form when the answer that you were looking for was an approximation (decimal form) answer. To achieve this all you have to do is hit the alpha button (the yellow button with a diamond in the center) and then enter which will give you your desired answer :-)

For the TI-Nspire and TI-Nspire CAS handheld units with TouchPad and
the TI-Nspire CX and TI-Nspire CX CAS:

• Hold down [doc] [enter] [EE].
• While holding these keys press [on].

Please Note: For TI-Nspire Family handheld units that

Hi, when I'm solving a trignometry exercise, using both degree and radian my Ti Nspire CX (not CAS) will only provide something like a aproximated number instead of giving me the answer in square roots or...

I am afraid you cannot do that. The CX has only two calculation modes AUTO and Approximate, while the CX CAS has these modes and a third one EXACT. That is the one that allows display of result with square roots and the symbol of Pi. Your best choice with the CX is to set the calculation mode to AUTO.

Why does the TI-nspire not give complete graphs of cube root and other franctional power functions?

I do not see why it would do that. Maybe you restricted the domain to positive values of the independent variable.
Anyway, my CX CAS has the latest OS version and it draws cube root for positive and negative values of x.
By the way the cube root is made up of one branch only, not 2 like the square root.
Here is a screen capture.

I am using Window XP. How to download software that includes a driver to my computer to use my TI-nspire CX ?

In the clamshell or the box the calculator came in, there is a CD. Use it to install the drivers and the TI Nspire Computer Link software. If it came with the TINspire CX student software you can install that too.

After that you can hook the calculator to the computer and run the TI Nspire Computer Link software or the Student/Teacher Software and it it will probe the USB port and find your calculator.
