Răspuns:

Explicație pas cu pas:

1) 1° = π/180°

a) 30° = 30°·π/180° = π/6

b) 45° =45°·π/180° = π/4

c) 60° =60°·π/180° = π/3

d) 270° = 270°·π/180° = 3·π/2

e) 540° = 540°·π/180° = 3·π

2) 1 radian = 180°/π

a) 3π rad = 3π·180°/π = 540°

b) 5π rad = 5π·180°/π = 900°

c) π/4 rad = π·180°/4π = 45°

d) π/6 rad = π·180°/6π = 30°

e) 5π/4 rad = 5π·180°/4π = 225°

f) 3π/4 rad = 3π·180°/4π = 135°
