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

Solution

periodicity

f (x) = 3 cos (x)

Solution

2 π

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}{∣ 1 ∣}

Simplify

= 2 π

Popular Examples

inflection 1/4 x^4-2x^2 inflection points

\frac{1}{4} x^{4} - 2 x^{2}

domain of f(x)=(x+5)/(x^2-9)domain

f (x) = \frac{x + 5}{x ^{2} - 9}

inverse of f(x)=(x-1)^2+5 inverse

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

intercepts of y=x^2 intercepts

y = x^{2}

inflection f(x)=-2x^6+15x^5 inflection points

f (x) = - 2 x^{6} + 15 x^{5}
