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

Solution

periodicity

f (x) = 2 - 4 cos (x)

Solution

2 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}{∣ 1 ∣}

Simplify

= 2 π

Popular Examples

extreme y=-1/2 x^2+4x-2 extreme points

y = - \frac{1}{2} x^{2} + 4 x - 2

domain of f(x)=(x^2+8x-9)/(x^2+3x-4)domain

f (x) = \frac{x ^{2} + 8 x - 9}{x ^{2} + 3 x - 4}

domain of (x^2+sqrt(x))^2 domain

(x^{2} + x)^{2}

range of y=2 range

y = 2

inverse of f(x)=x^5+3 inverse

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