Question

Identify the beginning of a sample period for the function

Answer 1

Given:

`f(t)\text{ = 2csc\lparen t + }(\pi)/(4))-1\text{ }`

The graph of f(t) is shown below:

From the graph, we can see that

`x=\text{ }(\pi)/(4)\text{ is a good start for the period of f\lparen t\rparen}`

Answer: Option D
