Normally, angles are interpreted according to the Angle mode

setting. However, you can specify an angle as degrees or

radians regardless of the Angle mode.
Suppose a series of trig calculations uses radians, but a few

use degrees. Rather than change from 

 to 

 Angle

mode and then back again, you can stay in the 

 Angle

mode and specify some angles as degrees.

In 

 Angle mode, calculate sin(p/3). Then, without

changing to the 

 Angle mode, calculate sin(60¡).

1. Select 

 Angle mode.

Likewise, you can use 

 to specify an angle as radians in the

 Angle mode.

60 is specified as degrees

even in Radian angle mode.
