Question

Which of the following describes the domain of y = tan x, where n is any integer?

A.x≠2nπ
B. x≠π/2+nπ
C. x≠nπ
D.x≠nπ/2

Answer 1

B. x≠π/2+nπ
i m not sure :(

Answer 2

Recall that the tangent function is:

\[tan(x) = \frac{sin(x)}{cos(x)}\]

So you cannot have a 0 in the denominator. Therefore you cannot have values of x for which cos(x) would be 0. When is cos(x) = 0?

Answer 3

tan pi/2 has no value
mathematicalpro's answer is correct
