inverse of 5cos(4x)

Solution

inverse

5 cos (4 x)

Solution

\frac{arccos ( \frac{x}{5} )}{4}

Solution steps

Solve for

cos (4 x), y = 5 cos (4 x)

cos (4 x) = \frac{y}{5}

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

4 x = arccos (\frac{y}{5})

Solve for

x, 4 x = arccos (\frac{y}{5})

\frac{arccos ( \frac{y}{5} )}{4}

Substitute

y = x

\frac{arccos ( \frac{x}{5} )}{4}
