Question

Expresse em radianos:

a) 30°
b) 45°
c) 60°
d) 120°
e) 135°
f) 150°
g) 225°
h) 300°​

Answer 1

a) 30° = 180/6 = π/6

b) 45° = 180/4 = π/4

c) 60° = π/3

d) 120°= 180 -60= π -π/3= 2π/3

e) 135° = 180 -45= π -π/4= 3π/4

f) 150°= 180 -30 = π -π/6= 5π/6

g) 225°= 180 +45= π +π/4=5π/4

h) 300°= 360 -60 =2π -π/3 = 5π/3
