periodicity of f(x)=-2cos(4pix)

Solution

periodicity

f (x) = - 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

asymptotes of f(x)=(19)/(1+7^{-x)}asymptotes

f (x) = \frac{19}{1 + 7 ^{- x}}

domain of f(x)=(x-7)^2 domain

f (x) = (x - 7)^{2}

domain of g(x)= 7/(sqrt(t))domain

g (x) = \frac{7}{t}

inverse of f(x)=(2x+1)/(3+x)inverse

f (x) = \frac{2 x + 1}{3 + x}

parity f(x)=x^2+16 parity

f (x) = x^{2} + 16
