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

Solution

periodicity

f (x) = - 3 cos (3 x)

Solution

\frac{2 π}{3}

Solution steps

Periodicity of

a \cdot cos (b x + c) + d = \frac{periodicity of cos ( x )}{∣ b ∣}

Periodicity of

cos (x)

is

2 π

= \frac{2 π}{∣ 3 ∣}

Simplify

= \frac{2 π}{3}

Popular Examples

domain of f(x)=sin(e^{-t})domain

f (x) = sin (e^{- t})

domain of f(x)=5^{x-3}domain

f (x) = 5^{x - 3}

critical f(x)=3x^2-6x-9 critical points

f (x) = 3 x^{2} - 6 x - 9

asymptotes of f(x)=(4x+6)/(x+3)asymptotes

f (x) = \frac{4 x + 6}{x + 3}

inverse of f(x)=-(x-1)^2-3 inverse

f (x) = - (x - 1)^{2} - 3
