& displays a menu (DEG RAD GRD) to express
angle measurements in degrees (default), radians, or
grads, respectively.
³ Problem
You probably know that 30 й=е/6 radians. In the default
Degree Mode, find the sine of 30 é. Then set the
calculator to Radian Mode and find the sine of å/6
radians.

You can override the Angle Mode with the / key.
Keep the calculator in Radian Mode and find the sine of
30
