inverse of 3cos(2x)

Solution

inverse

3 cos (2 x)

Solution

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

Solution steps

Solve for

cos (2 x), y = 3 cos (2 x)

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

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

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

Solve for

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

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

Substitute

y = x

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