periodicity of 5cos(4x)

Solution

periodicity

5 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

inverse of f(x)=(x-8)/5 inverse

f (x) = \frac{x - 8}{5}

inverse of f(x)=(x+14)/(x-7)inverse

f (x) = \frac{x + 14}{x - 7}

domain of (x^2+1)/(x^2-1)domain

\frac{x ^{2} + 1}{x ^{2} - 1}

extreme f(x)=x^4-24x^2 extreme points

f (x) = x^{4} - 24 x^{2}

domain of y=(x/(x-1))domain

y = (\frac{x}{x - 1})
