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

extreme (x-3)^{2/3}extreme points

(x - 3)^{\frac{2}{3}}

parity y=7cos(t)-5t^{cos(t)},0<= t<= 7 parity

y = 7 cos (t) - 5 t^{c o s (t)}, 0 \leq t \leq 7

domain of (3x)/(x^2-x-2)domain

\frac{3 x}{x ^{2} - x - 2}

extreme f(x)=sec(x-pi/4)extreme points

f (x) = sec (x - \frac{π}{4})

periodicity of f(x)=5sin(2x)periodicity

f (x) = 5 sin (2 x)
