periodicity of f(x)=2cos(6x+pi/2)

periodicity

f (x) = 2 cos (6 x + \frac{π}{2})

\frac{π}{3}

Solution steps

Periodicity of

a \cdot cos (b x + c) + d = \frac{periodicity of cos ( x )}{∣ b ∣}

Periodicity of

cos (x)

2 π

= \frac{2 π}{∣ 6 ∣}

Simplify

= \frac{π}{3}

(250, - 200), (350, - 500)

\frac{- 6 + 3 x ^{2}}{x ^{2} - 1}

f (x) = 5 x + 3

12 x + 3 y = - 3

f (x) = \frac{1}{6} x^{3} - 5
