Question

What is the frequency of `f(theta)= sin 24 t - cos 32 t`?

Answer 1

`pi/2`

Explanation:

Period of `sin (24t)` --> `(2pi)/24 = pi/12`
Petiod of `cos (32t)` --> `(2pi)/32 = pi/16`
Period of f(t) is least common multiple of pi/12 and pi/16.
It is `pi/2`
`pi/12 ... X.(6) --> pi/2`
`pi/16 ... X.(8) --> pi/2`
