periodicity of-2cos(4pix)

Solution

periodicity

- 2 cos (4 π x)

Solution

\frac{1}{2}

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}{∣ 4 π ∣}

Simplify

= \frac{1}{2}

Popular Examples

symmetry y=-6x^2-6x symmetry

y = - 6 x^{2} - 6 x

inverse of f(x)=((e^x-e^{-x}))/2 inverse

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

domain of f(x)=-x^2+3x+5 domain

f (x) = - x^{2} + 3 x + 5
