<PRE><B>Question 93990</B>
express 75degrees in radians
----------------
Here is the way to remember the conversion.
pi radians = 180 degrees
Dividing by pi you get 1 radian = 180/pi degrees
OR
Dividing by 180 you get 1 degree = pi/180 radian
----------------------
Your Problem:
Start with 1 degree = pi/180 radian
Multiply both sides by 75 to get:
75 degrees = 75(pi/180) radians
75 degrees = (5/12)pi radians
