ITrigonometric Functions (sin, cos, tan) and Inverse TrigonometricFunctions (sin–1, cos–1, tan–1)

The first four examples below use “Degree” (indicated by “Deg” in the status bar) as the angle unit setting. The final example uses “Radian” (indicated by “Rad”). For details about these settings, see “1-9 Configuring Application Format Settings”.

Tip

•The angle unit setting you specify remains in effect until you change it.

•To move between entry boxes in a 2D math symbol you can use the cursor keys or tap inside a box.
