Question

What is the frequency of the function y = -5cos6x?

Answer 1

You can use the following equation
\[\large y=A \cos Bx\]
where the period
\[\large T=\frac{2 \pi}{B}\]
to find the period of the given function by plugging in values, giving the period
\[\large T=\frac{2\pi}{6}\]
The frequency is the reciprocal of the period. Therefore
\[\large f=\frac{6}{2\pi}\]

Answer 2

which can be simplified to
\[\large f=\frac{3}{\pi}\]
