periodicity of y=cos(2x)

Solution

periodicity

y = cos (2 x)

Solution

π

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}{∣ 2 ∣}

Simplify

= π

Popular Examples

inverse of f(x)=sqrt(2x+3)inverse

f (x) = 2 x + 3

f (x) = 3 x + 4

range of f(x)=sqrt(81-x^2)range

f (x) = 81 - x^{2}

domain of f(x)=log_{6}(x-3)domain

f (x) = lo g_{6} (x - 3)

critical f(x)=(x^2)/(4x+4)critical points

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