Answer the following. (a) Find an angle between 0° and 360° that is coterminal with 390. (b) Find an angle between 0 and 2 that is coterminal with 4 -_, Give exact values for your answers. (b) radians Clear Undo Help

Solution

(a)

an angle between 0^o and 360^o that is coterminal with 390^o is = 390^o - 360^o

an angle between 0^o and 360^o that is coterminal with  390^o is  = 30^o

(b)

an angle between 0 and 2that is coterminal with -4_/3 is  = -(4_/3)  +2

an angle between 0 and 2that is coterminal with -4_/3 is  = 2_/3 radians
