The period of the tangent function is given by:
b) 2pi
It is the distance between the repetition of the function. If a function is defined on an interval and said to be periodic, the period is the length of the interval.
In this problem, the interval is [tex][-\pi, \pi][/tex], and after that the values will start repeating, hence the period is:
[tex]p = \pi - (-\pi) = 2\pi[/tex]
Thus option b is correct, as the period is of [tex]2\pi[/tex].
