inverse of-6cos(7x)

Solution

inverse

- 6 cos (7 x)

Solution

\frac{arccos ( - \frac{x}{6} )}{7}

Solution steps

Solve for

cos (7 x), y = - 6 cos (7 x)

cos (7 x) = - \frac{y}{6}

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

7 x = arccos (- \frac{y}{6})

Solve for

x, 7 x = arccos (- \frac{y}{6})

\frac{arccos ( - \frac{y}{6} )}{7}

Substitute

y = x

\frac{arccos ( - \frac{x}{6} )}{7}

Popular Examples

domain of f(x)= 3/(x^2+4x-45)domain

f (x) = \frac{3}{x ^{2} + 4 x - 45}

shift f(x)=6cos(1/5 pix-pi)+4 shift

f (x) = 6 cos (\frac{1}{5} π x - π) + 4

domain of f(x)=x^{5/4}domain

f (x) = x^{\frac{5}{4}}

domain of f(x)= x/(sqrt(4-x^2))domain

f (x) = \frac{x}{4 - x ^{2}}

asymptotes of f(x)= 7/(x^2-2x-24)asymptotes

f (x) = \frac{7}{x ^{2} - 2 x - 24}
