arcsin(3x-pi)= 1/2

Solução

arcsin (3 x - π) = \frac{1}{2}

Solução

x = \frac{sin ( \frac{1}{2} ) + π}{3}

Passos da solução

arcsin (3 x - π) = \frac{1}{2}

Aplique as propriedades trigonométricas inversas

arcsin (3 x - π) = \frac{1}{2}

arcsin (x) = a \Rightarrow x = sin (a)

3 x - π = sin (\frac{1}{2})

3 x - π = sin (\frac{1}{2})

Resolver

3 x - π = sin (\frac{1}{2}) : x = \frac{sin ( \frac{1}{2} ) + π}{3}

3 x - π = sin (\frac{1}{2})

Mova

π

para o lado direito

3 x - π = sin (\frac{1}{2})

Adicionar

π

a ambos os lados

3 x - π + π = sin (\frac{1}{2}) + π

Simplificar

3 x = sin (\frac{1}{2}) + π

3 x = sin (\frac{1}{2}) + π

Dividir ambos os lados por

3

3 x = sin (\frac{1}{2}) + π

Dividir ambos os lados por

3

\frac{3 x}{3} = \frac{sin ( \frac{1}{2} )}{3} + \frac{π}{3}

Simplificar

\frac{3 x}{3} = \frac{sin ( \frac{1}{2} )}{3} + \frac{π}{3}

Simplificar

\frac{3 x}{3} : x

\frac{3 x}{3}

Dividir:

\frac{3}{3} = 1

= x

Simplificar

\frac{sin ( \frac{1}{2} )}{3} + \frac{π}{3} : \frac{sin ( \frac{1}{2} ) + π}{3}

\frac{sin ( \frac{1}{2} )}{3} + \frac{π}{3}

Já que os denominadores são iguais, combinar as frações:

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

= \frac{sin ( \frac{1}{2} ) + π}{3}

x = \frac{sin ( \frac{1}{2} ) + π}{3}

x = \frac{sin ( \frac{1}{2} ) + π}{3}

x = \frac{sin ( \frac{1}{2} ) + π}{3}

x = \frac{sin ( \frac{1}{2} ) + π}{3}
