periodicity of f(t)=2.3cos(0.25t)

periodicity

f (t) = 2.3 cos (0.25 t)

25.13274 \dots

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}{∣ 0.25 ∣}

Simplify

= 25.13274 \dots

f (x) = x^{2} + 4 x - 12

(5.6) (1.3)

\frac{x ( x - 5 )}{2 ( x + 3 )}

f (x) = \frac{x + 2}{x + 8}

f (x) = \frac{1}{6 x ^{2} - x - 12}
