\frac{120}{119}

Notación decimal

1.00840 \dots

Pasos de solución

tan (2 arcsin (- \frac{12}{13}))

Re-escribir usando identidades trigonométricas:

\frac{2 tan ( arcsin ( \frac{12}{13} ) )}{tan ^{2} ( arcsin ( \frac{12}{13} ) ) - 1}

tan (2 arcsin (- \frac{12}{13}))

Utilizar la identidad trigonométrica del ángulo doble:

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

= \frac{2 tan ( arcsin ( - \frac{12}{13} ) )}{1 - tan ^{2} ( arcsin ( - \frac{12}{13} ) )}

\frac{2 tan ( arcsin ( - \frac{12}{13} ) )}{1 - tan ^{2} ( arcsin ( - \frac{12}{13} ) )} = - \frac{2 tan ( arcsin ( - \frac{12}{13} ) )}{tan ^{2} ( arcsin ( - \frac{12}{13} ) ) - 1}

Utilizar la siguiente propiedad:

arcsin (- x) = - arcsin (x)

arcsin (- \frac{12}{13}) = - arcsin (\frac{12}{13})

= - \frac{2 tan ( arcsin ( - \frac{12}{13} ) )}{tan ^{2} ( - arcsin ( \frac{12}{13} ) ) - 1}

Utilizar la siguiente propiedad:

tan (- x) = - tan (x)

tan (- arcsin (\frac{12}{13})) = - tan (arcsin (\frac{12}{13}))

= - \frac{2 tan ( arcsin ( - \frac{12}{13} ) )}{( - tan ( arcsin ( \frac{12}{13} ) ) ) ^{2} - 1}

Utilizar la siguiente propiedad:

arcsin (- x) = - arcsin (x)

arcsin (- \frac{12}{13}) = - arcsin (\frac{12}{13})

= - \frac{2 tan ( - arcsin ( \frac{12}{13} ) )}{( - tan ( arcsin ( \frac{12}{13} ) ) ) ^{2} - 1}

Utilizar la siguiente propiedad:

tan (- x) = - tan (x)

tan (- arcsin (\frac{12}{13})) = - tan (arcsin (\frac{12}{13}))

= - \frac{2 ( - tan ( arcsin ( \frac{12}{13} ) ) )}{( - tan ( arcsin ( \frac{12}{13} ) ) ) ^{2} - 1}

Simplificar

= \frac{2 tan ( arcsin ( \frac{12}{13} ) )}{tan ^{2} ( arcsin ( \frac{12}{13} ) ) - 1}

= \frac{2 tan ( arcsin ( \frac{12}{13} ) )}{tan ^{2} ( arcsin ( \frac{12}{13} ) ) - 1}

Re-escribir usando identidades trigonométricas:

tan (arcsin (\frac{12}{13})) = \frac{12}{5}

tan (arcsin (\frac{12}{13}))

Re-escribir usando identidades trigonométricas:

tan (arcsin (\frac{12}{13})) = \frac{( \frac{12}{13} ) 1 - ( \frac{12}{13} ) ^{2}}{1 - ( \frac{12}{13} ) ^{2}}

Usar la siguiente identidad:

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

= \frac{( \frac{12}{13} ) 1 - ( \frac{12}{13} ) ^{2}}{1 - ( \frac{12}{13} ) ^{2}}

Simplificar

\frac{144}{25} - 1

en una fracción:

\frac{119}{25}

\frac{144}{25} - 1

Convertir a fracción:

1 = \frac{1 \cdot 25}{25}

= \frac{144}{25} - \frac{1 \cdot 25}{25}

Ya que los denominadores son iguales, combinar las fracciones:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{144 - 1 \cdot 25}{25}

144 - 1 \cdot 25 = 119

144 - 1 \cdot 25

Multiplicar los numeros:

1 \cdot 25 = 25

= 144 - 25

Restar:

144 - 25 = 119

= 119

= \frac{119}{25}

= \frac{24}{5 \cdot \frac{119}{25}}

Multiplicar

5 \cdot \frac{119}{25} : \frac{119}{5}

5 \cdot \frac{119}{25}

Multiplicar fracciones:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{119 \cdot 5}{25}

Multiplicar los numeros:

119 \cdot 5 = 595

= \frac{595}{25}

Eliminar los terminos comunes:

5

= \frac{119}{5}

= \frac{24}{\frac{119}{5}}

Aplicar las propiedades de las fracciones:

\frac{a}{\frac{b}{c}} = \frac{a \cdot c}{b}

= \frac{24 \cdot 5}{119}

Multiplicar los numeros:

24 \cdot 5 = 120

= \frac{120}{119}

= \frac{120}{119}
