periodicity of f(x)=cos(x)*cos(2x)

periodicity

f (x) = cos (x) \cdot cos (2 x)

2 π

Solution steps

cos (x) \cdot cos (2 x)

is composed of the following functions and periods:

cos (x)

with periodicity of

2 π

The compound periodicity is:

= 2 π

f (x) = x^{3} + x - 4

f (x) = - \frac{5}{x}

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

f (x) = - x^{2} + 4 x - 8

y = (2 x + 3) (x - 1)^{2}

What is the periodicity of f(x)=cos(x)*cos(2x) ?
The periodicity of f(x)=cos(x)*cos(2x) is 2pi
