11.33=1.59cos(0.99(x-182))+12.14

Solução

11.33 = 1.59 cos (0.9 9^{\circ} (x - 18 2^{\circ})) + 12.14

Solução

x = 18 2^{\circ} + \frac{4000 n}{11} + \frac{2000 \cdot 2.10532 \dots}{198 0 ^{\circ}}, x = 18 2^{\circ} + \frac{4000 n}{11} - \frac{2000 \cdot 2.10532 \dots}{198 0 ^{\circ}}

Radianos

x = \frac{91 π}{90} + \frac{2000 \cdot 2.10532 \dots}{11 π} + \frac{4000}{11} n, x = \frac{91 π}{90} - \frac{2000 \cdot 2.10532 \dots}{11 π} + \frac{4000}{11} n
