What is the frequency of #f(theta)= sin 24 t - cos 45 t #?
The epriod for both sin k t and cos kt is
So, the separate periods for the oscillations #sin 24t and cos 45t are
The period P for the compounded oscillation
positive integer multiple of
Easily, M= 720 and N=675, making P = 30pi#.
So, the frequency
See how P is least.
Here, if Pis halved to
