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.

The expression a function acts on (i.e. what is inside the function) is called its argument. The arguments of some functions such as y=ax, y=ax^2 can have any real value. However some functions have arguments that must be in a specified domain: they are restricted to some specified intervals. For example y=square root (x) can act on any positive value, but if you feed it a negative value it is out of the correct domain.

The differentiation rules for trigonometric functions you have been taught (ex: derivative of sin(x) is cos(x) ) are correct if the angle unit is in radians. If you use any other angle units (ex: degrees, grads) there will be a conversion factor :derivative of sin(ax) with respect to x is a.cos(ax).
Hope that helps

You do not. The TINspire with TI-84 keyboard works as a TI-84 Silver edition. Its OS is update when the TINspire OS is updated. The Ti 84 OS's you find on the TI website are not for the TINspire with TI84 keyboard.

Turn the calculator ON, press Settings, It will show you an icon for a battery with a broken arrow (Zap). It will also show the percentage of charge.

Too bad you cannot call Qualinet, because they only do houses. Just joking. Let it dry and try later. I might work again.

You check the calculator settings. It will show you the percentage of battery energy. If the calculator refuses to turn on, the battery are dead.
