periodicity of f(x)=-2cos(3x)

Solution

periodicity

f (x) = - 2 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

7 sin (x) + 7 cos (x)

domain of h(x)=2(x-1)^3+5 domain

h (x) = 2 (x - 1)^{3} + 5

domain of f(x)= 1/(sqrt(17x-34))domain

f (x) = \frac{1}{17 x - 34}

domain of f(x)=sqrt(-x^3-2x^2+16x+32)domain

f (x) = - x^{3} - 2 x^{2} + 16 x + 32
