Answer:

Correct choice is A

Step-by-step explanation:

The period of the function [tex]f(t)=a\cot (bt+c)[/tex] is always

[tex]T=\dfrac{\pi}{b}[/tex]

(coefficients a and c do not influence).

In your case, for the function [tex]f(t)=3\cot (\pi t)[/tex] the period is [tex]\dfrac{\pi}{\pi}=1.[/tex]

Step-by-step explanation:

Period of a sinusoidal function (here we're taking the cot x function) is [tex]\pi[/tex] divided by the argument after cot ( the argument here is [tex]\pi[/tex])


Hence the period is:

Period =  [tex]\frac{\pi}{\pi}=1[/tex]
