Question

Identify the period for the trigonometric function: f (t) = 3cot(πt).

Answer 1

Answer:

Correct choice is A

Step-by-step explanation:

The period of the function $f(t)=a\cot (bt+c)$ is always

$T=\dfrac{\pi}{b}$

(coefficients a and c do not influence).

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

Answer 2

Answer:

1

Step-by-step explanation:

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

Hence the period is:

Period =  $\frac{\pi}{\pi}=1$
