Question

Accepted Answer

Para converter graus em radianos, usamos a fórmula:

$$
\text{radianos} = \text{graus} \times \frac{\pi}{180}
$$

a) $60^\circ$: 
$$
60 \times \frac{\pi}{180} = \frac{\pi}{3}
$$

b) $45^\circ$: 
$$
45 \times \frac{\pi}{180} = \frac{\pi}{4}
$$

c) $210^\circ$: 
$$
210 \times \frac{\pi}{180} = \frac{7\pi}{6}
$$

d) $300^\circ$: 
$$
300 \times \frac{\pi}{180} = \frac{5\pi}{3}
$$

e) $150^\circ$: 
$$
150 \times \frac{\pi}{180} = \frac{5\pi}{6}
$$

f) $330^\circ$: 
$$
330 \times \frac{\pi}{180} = \frac{11\pi}{6}
$$

g) $315^\circ$: 
$$
315 \times \frac{\pi}{180} = \frac{7\pi}{4}
$$

h) $90^\circ$: 
$$
90 \times \frac{\pi}{180} = \frac{\pi}{2}
$$

i) $270^\circ$: 
$$
270 \times \frac{\pi}{180} = \frac{3\pi}{2}
$$

j) $15^\circ$: 
$$
15 \times \frac{\pi}{180} = \frac{\pi}{12}
$$
