Question

converta em radianos: a) 45° b) 120° c) 210° d) 15° e) 150° f) 315° g) 330° h) 310°

Answer 1

a) 45° = (45/180).π = (1/4).π = π/4
b) 120° =(120/180).π= (2/3)π= 2π/3
c) 210° =(21/18)π = 7π/6
d) 15° = (15/180)π= (1/12)π = π/12
e) 150° =(15/18)π=(5/6)π = 5π/6
f) 315° = (360-45)=(2π -π/4)= 7π/4
g) 330° =(33/18)π = 11π/6
h) 310°= (31/18)π = 31π/18
