inverse of 3cos^2(x)

Solution

inverse

3 cos^{2} (x)

Solution

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

Solution steps

Solve for

cos (x), y = 3 cos^{2} (x)

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

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

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

Substitute

y = x

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