periodicity of f(x)=2cos(1/2 x+pi)

periodicity

f (x) = 2 cos (\frac{1}{2} x + π)

4 π

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{1}{2}}

Simplify

= 4 π

f (x) = cos (π x)

f (x) = ln (x - 1)

(5.5) (2.1)

f (x) = - 2 x + 6

arccos (x)
