inverse of+3cos(5x-9)

Solution

inverse

+ 3 cos (5 x - 9)

Solution

\frac{arccos ( \frac{x}{3} ) + 9}{5}

Solution steps

Solve for

cos (5 x - 9), y = + 3 cos (5 x - 9)

cos (5 x - 9) = \frac{y}{3}

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

5 x - 9 = arccos (\frac{y}{3})

Solve for

x, 5 x - 9 = arccos (\frac{y}{3})

\frac{arccos ( \frac{y}{3} ) + 9}{5}

Substitute

y = x

\frac{arccos ( \frac{x}{3} ) + 9}{5}
