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

Solution

periodicity

f (x) = - cos (4 x)

Solution

\frac{π}{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 ∣}

Simplify

= \frac{π}{2}

Popular Examples

domain of f(x)=4x^2+2 domain

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

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

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

extreme f(x)=x^3-6x^2+13 extreme points

f (x) = x^{3} - 6 x^{2} + 13

intercepts of f(x)=7x-2y=-2 intercepts

f (x) = 7 x - 2 y = - 2

domain of g(x)=sqrt(4x+48)domain

g (x) = 4 x + 48
