inverse of f(x)=pi-3*arcsin(2x-1)

inverse

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

Solution steps

Solve for

arcsin (2 x - 1), y = π - 3 \cdot arcsin (2 x - 1)

arcsin (2 x - 1) = - \frac{y - π}{3}

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

2 x - 1 = sin (- \frac{y - π}{3})

Solve for

x, 2 x - 1 = sin (- \frac{y - π}{3})

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

Substitute

y = x

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