periodicity of-7/9 cos(9/8 x)

Solution

periodicity

- \frac{7}{9} cos (\frac{9}{8} x)

Solution

\frac{16 π}{9}

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}{\frac{9}{8}}

Simplify

= \frac{16 π}{9}
