Angle settings

By default, TI-Nspire uses the angle unit defined in the document settings. If the input includes a unit, it is converted to the unit specified in the settings. On Windows, the ° symbol can be entered using CTRL + *, and Mac keyboards include a dedicated key. Units can also be entered using @d or @r.

Computer view: The angle unit is shown at the bottom of the screen. Double-click Settings to open the document settings. Selecting Make Default applies the same setting to new documents. Selecting OK applies the settings only to the current document.

Computer view angle settings — In the computer view, the angle unit is shown at the bottom of the screen and settings can be accessed by double-clicking *Settings*.

Handheld view: The angle unit can be changed directly by tapping the unit shown at the top of the screen (e.g. RAD).

Handheld view angle unit — In the handheld view, the angle unit can be changed directly from the top of the screen.

Tip: The angle setting of a math box can also be changed per calculation. This is useful when the result is needed in different units. Unit conversion can also be performed using the commands @>DD and @>Rad.

Math box angle setting — The angle unit can also be changed for a single math box.
