>>id=example1 class=question margin=10px frame round<< (a) There are 360° in one complete cycle (i.e. one revolution). Hence there are 360/4 or 90° in one quarter of a cycle. (b) There are 2π radians in one complete cycle (i.e. one revolution).

>>id=example2 class=question margin=10px frame round<< To convert from degrees to radians, divide by 57.3. Hence 215° is equivalent to 215/57.3 = 3.75 radians. >><< >>frame round<< Example 3: A satellite tracking antenna turns through an angle of 2.5 radians. What is this angle expressed in degrees? >><<
>>id=example3 class=question margin=10px frame round<< To convert from radians to degrees, multiply by 57.3. Hence 2.5 radians is equivalent to 2.5 x 57.3 = 143.25°. >><<(:nl:)(:table style="clear:both":)
