inverse of 2arccos(x/3)

Solution

inverse

2 arccos (\frac{x}{3})

Solution

3 cos (\frac{x}{2})

Solution steps

Solve for

arccos (\frac{x}{3}), y = 2 arccos (\frac{x}{3})

arccos (\frac{x}{3}) = \frac{y}{2}

arccos (a) = b \Rightarrow a = cos (b)

\frac{x}{3} = cos (\frac{y}{2})

Solve for

x, \frac{x}{3} = cos (\frac{y}{2})

3 cos (\frac{y}{2})

Substitute

y = x

3 cos (\frac{x}{2})
