degrees, find the sine of 30 ¡ . Then set the calculator to radian
mode and calculate the sine of p / 6 radians.
Note: Press - to clear the screen between problems.
Retain radian mode on the calculator and calculate the sine of
30
¡ . Change the calculator to degree mode and find the sine
of p / 6 radians.
