tan(2x)-1/(tan(x))=0

Solución

tan (2 x) - \frac{1}{tan ( x )} = 0

x = 0.52359 \dots + πn, x = - 0.52359 \dots + πn

Pasos de solución

tan (2 x) - \frac{1}{tan ( x )} = 0

Simplificar

tan (2 x) - \frac{1}{tan ( x )} : \frac{tan ( 2 x ) tan ( x ) - 1}{tan ( x )}

\frac{tan ( 2 x ) tan ( x ) - 1}{tan ( x )} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0

tan (2 x) tan (x) - 1 = 0

Re-escribir usando identidades trigonométricas

- 1 + \frac{2 tan ^{2} ( x )}{1 - tan ^{2} ( x )} = 0

Usando el método de sustitución

tan (x) = \frac{1}{3}, tan (x) = - \frac{1}{3}

tan (x) = \frac{1}{3} : x = arctan (\frac{1}{3}) + πn

tan (x) = - \frac{1}{3} : x = arctan (- \frac{1}{3}) + πn

Combinar toda las soluciones

x = arctan (\frac{1}{3}) + πn, x = arctan (- \frac{1}{3}) + πn
