periodicity of 1200+400cos((pit)/3)

periodicity

1200 + 400 cos (\frac{π t}{3})

6

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}{\frac{π}{3}}

Simplify

= 6

f (x) = x^{2} - 10 x + 21

9 x^{6} - x^{5} - 2 x^{3} + 2

f (x) = \frac{x ^{3}}{x ^{2}}

(- 2, 4), (13, 10)

h (x) = ln (x + 6)
