What is the frequency of #f(theta)= sin 12 t - cos 7 t #?

Question:

What is the frequency of #f(theta)= sin 12 t - cos 7 t #?

Answers

#2pi#

Explanation:

Frequency of sin 12t --> (2pi)/12 = pi/6
Frequency of cos (7t) --> (2pi/7)
Frequency of f(t) --># 2pi#
#2pi# is least multiple.
#(pi/6)# x 12 --> #2pi#
#(2pi/7)# x 7 --> #2pi#
