periodicity of 2cos(pix)

Solution

periodicity

2 cos (π x)

Solution

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}{∣ π ∣}

Simplify

= 2

Popular Examples

inflection f(x)=x^2-x+5 inflection points

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

shift f(x)= 1/2 sin(x+pi/4)shift

f (x) = \frac{1}{2} sin (x + \frac{π}{4})

domain of f(x)=-sqrt(3x-12)-5 domain

f (x) = - 3 x - 12 - 5
