inverse of cos(4x)

Solution

inverse

cos (4 x)

Solution

\frac{arccos ( x )}{4}

Solution steps

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

4 x = arccos (y)

Solve for

x, 4 x = arccos (y)

\frac{arccos ( y )}{4}

Substitute

y = x

\frac{arccos ( x )}{4}

Popular Examples

periodicity of f(x)=3cos(x)periodicity

f (x) = 3 cos (x)

inflection 1/4 x^4-2x^2 inflection points

\frac{1}{4} x^{4} - 2 x^{2}

domain of f(x)=(x+5)/(x^2-9)domain

f (x) = \frac{x + 5}{x ^{2} - 9}

inverse of f(x)=(x-1)^2+5 inverse

f (x) = (x - 1)^{2} + 5

intercepts of y=x^2 intercepts

y = x^{2}
