periodicity of cos(3x)

Solution

periodicity

cos (3 x)

Solution

\frac{2 π}{3}

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}{∣ 3 ∣}

Simplify

= \frac{2 π}{3}

Popular Examples

extreme f(x)=2x^3-3x^2-12x extreme points

f (x) = 2 x^{3} - 3 x^{2} - 12 x

monotone sqrt(x+2)monotone intervals

x + 2

domain of (sqrt(x+1))/(|x|)domain

\frac{x + 1}{∣ x ∣}

extreme f(x)=x^4-4x^3+10 extreme points

f (x) = x^{4} - 4 x^{3} + 10

domain of f(x)= 1/(sqrt(2x+1))domain

f (x) = \frac{1}{2 x + 1}
