Section 4.1

 

39. correct
40.
-48.27 degree= -0.84247 radians

41.
-0.54 degree=-0.00942 radians

42. 345 degree =6.02139

 

Can you please show the step by step reply for 40 through 42?

 

40.

degrees * π/180 = radians

convert: -48.27 degree

=-48.27 * π/180

=-48.27* 0.017453292519943295

= -0.84247 radians

41.
-0.54 degree to radian

=-0.54* π/180
=-0.54* 0.017453292519943295
=-0.00942 radians

42.

345 degree
345* π/180
=345* 0.017453292519943295
=6.02139

 

Very easy. I probably rushed through the questions. We are sailing through the Ron Larson textbook (with occasional problems from the David Cohen book).
