0.56=tan^2(45+x/2)

Solución

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

Solución

x = 2 \cdot 0.64243 \dots + 36 0^{\circ} n - 9 0^{\circ}, x = - 2 \cdot 0.64243 \dots + 36 0^{\circ} n - 9 0^{\circ}

Radianes

x = 2 \cdot 0.64243 \dots - \frac{π}{2} + 2 πn, x = - 2 \cdot 0.64243 \dots - \frac{π}{2} + 2 πn

Pasos de solución

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

Intercambiar lados

tan^{2} (4 5^{\circ} + \frac{x}{2}) = 0.56

Usando el método de sustitución

tan^{2} (4 5^{\circ} + \frac{x}{2}) = 0.56

Sea:

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

u^{2} = 0.56

u^{2} = 0.56 : u = 0.56, u = - 0.56

u^{2} = 0.56

Para

x^{2} = f (a)

las soluciones son

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

u = 0.56, u = - 0.56

Sustituir en la ecuación

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

tan (4 5^{\circ} + \frac{x}{2}) = 0.56, tan (4 5^{\circ} + \frac{x}{2}) = - 0.56

tan (4 5^{\circ} + \frac{x}{2}) = 0.56, tan (4 5^{\circ} + \frac{x}{2}) = - 0.56

tan (4 5^{\circ} + \frac{x}{2}) = 0.56 : x = 2 arctan (0.56) + 36 0^{\circ} n - 9 0^{\circ}

tan (4 5^{\circ} + \frac{x}{2}) = 0.56

Aplicar propiedades trigonométricas inversas

tan (4 5^{\circ} + \frac{x}{2}) = 0.56

Soluciones generales para

tan (4 5^{\circ} + \frac{x}{2}) = 0.56

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

4 5^{\circ} + \frac{x}{2} = arctan (0.56) + 18 0^{\circ} n

4 5^{\circ} + \frac{x}{2} = arctan (0.56) + 18 0^{\circ} n

Resolver

4 5^{\circ} + \frac{x}{2} = arctan (0.56) + 18 0^{\circ} n : x = 2 arctan (0.56) + 36 0^{\circ} n - 9 0^{\circ}
