tan^2(45+x/3)=0.58

Solução

tan^{2} (4 5^{\circ} + \frac{x}{3}) = 0.58

Solução

x = 3 \cdot 0.65086 \dots + 54 0^{\circ} n - 13 5^{\circ}, x = - 3 \cdot 0.65086 \dots + 54 0^{\circ} n - 13 5^{\circ}

Radianos

x = 3 \cdot 0.65086 \dots - \frac{3 π}{4} + 3 πn, x = - 3 \cdot 0.65086 \dots - \frac{3 π}{4} + 3 πn

Passos da solução

tan^{2} (4 5^{\circ} + \frac{x}{3}) = 0.58

Usando o método de substituição

tan^{2} (4 5^{\circ} + \frac{x}{3}) = 0.58

Sea:

tan (4 5^{\circ} + \frac{x}{3}) = u

u^{2} = 0.58

u^{2} = 0.58 : u = 0.58, u = - 0.58

u^{2} = 0.58

Para

x^{2} = f (a)

as soluções são

x = f (a), - f (a)

u = 0.58, u = - 0.58

Substituir na equação

u = tan (4 5^{\circ} + \frac{x}{3})

tan (4 5^{\circ} + \frac{x}{3}) = 0.58, tan (4 5^{\circ} + \frac{x}{3}) = - 0.58

tan (4 5^{\circ} + \frac{x}{3}) = 0.58, tan (4 5^{\circ} + \frac{x}{3}) = - 0.58

tan (4 5^{\circ} + \frac{x}{3}) = 0.58 : x = 3 arctan (0.58) + 54 0^{\circ} n - 13 5^{\circ}

tan (4 5^{\circ} + \frac{x}{3}) = 0.58

Aplique as propriedades trigonométricas inversas

tan (4 5^{\circ} + \frac{x}{3}) = 0.58

Soluções gerais para

tan (4 5^{\circ} + \frac{x}{3}) = 0.58

tan (x) = a \Rightarrow x = arctan (a) + 18 0^{\circ} n

4 5^{\circ} + \frac{x}{3} = arctan (0.58) + 18 0^{\circ} n

4 5^{\circ} + \frac{x}{3} = arctan (0.58) + 18 0^{\circ} n

Resolver

4 5^{\circ} + \frac{x}{3} = arctan (0.58) + 18 0^{\circ} n : x = 3 arctan (0.58) + 54 0^{\circ} n - 13 5^{\circ}
