periodicity of f(x)=5cos(4x)

Solution

periodicity

f (x) = 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)=2x+15 inverse

f (x) = 2 x + 15

intercepts of f(x)=(x+1)/x intercepts

f (x) = \frac{x + 1}{x}

domain of sqrt(((9+x))/(9-x))domain

\frac{( 9 + x )}{9 - x}

inverse of f(x)=\sqrt[10]{x}inverse

domain of f(x)= x/(x^2+36)domain

f (x) = \frac{x}{x ^{2} + 36}
