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

Correct choice is A

Step-by-step explanation:

The period of the function is always

(coefficients a and c do not influence).

In your case, for the function the period is

1

Step-by-step explanation:

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

Hence the period is:

Period =  

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
