INTRO TO RADIANS
INTRO TO RADIANS
Important formula:
c = 2πr
Notes:
- π radians in half a circle
- π radians = 180 degrees
EX)
- πθ = 180
---- ------
π π
CONVERTING RADIANS TO DEGREES
- Multiply # of radians by 180/π
DEGREES TO RADIANS
π radians/180 = 1 degree
- multiply # of degrees by π radians/180 to figure out the number of radians
