tan^{22}(x)=sec^2(x)-1

Solución

tan^{22} (x) = sec^{2} (x) - 1

Solución

x = πn, x = \frac{π}{4} + πn, x = \frac{3 π}{4} + πn

Grados

x = 0^{\circ} + 18 0^{\circ} n, x = 4 5^{\circ} + 18 0^{\circ} n, x = 13 5^{\circ} + 18 0^{\circ} n

Pasos de solución

tan^{22} (x) = sec^{2} (x) - 1

Restar

sec^{2} (x) - 1

de ambos lados

tan^{22} (x) - sec^{2} (x) + 1 = 0

Re-escribir usando identidades trigonométricas

1 - sec^{2} (x) + tan^{22} (x)

Utilizar la identidad pitagórica:

sec^{2} (x) = tan^{2} (x) + 1

sec^{2} (x) - 1 = tan^{2} (x)

= tan^{22} (x) - tan^{2} (x)

tan^{22} (x) - tan^{2} (x) = 0

Usando el método de sustitución

tan^{22} (x) - tan^{2} (x) = 0

Sea:

tan (x) = u

u^{22} - u^{2} = 0

u^{22} - u^{2} = 0 : u = 0, u = 1, u = - 1

u^{22} - u^{2} = 0
