What is the period of #f(t)=sin( t /44 )+ cos( (7t)/24 ) #?
The period for both sin kt and cos kt i
Here, the periods for the separate oscillations #sin(t/44) and cos
The period P for the compounded oscillation f(t) is given by
multiples to give P as the least even positive integer.
See how it works.
Note the if P is halved , the second term would become its negative.
