inverse of y=-3cos(4x)

Solution

inverse

y = - 3 cos (4 x)

Solution

\frac{arccos ( - \frac{x}{3} )}{4}

Solution steps

Solve for

cos (4 x), y = - 3 cos (4 x)

cos (4 x) = - \frac{y}{3}

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

4 x = arccos (- \frac{y}{3})

Solve for

x, 4 x = arccos (- \frac{y}{3})

\frac{arccos ( - \frac{y}{3} )}{4}

Substitute

y = x

\frac{arccos ( - \frac{x}{3} )}{4}
