That set is theI found in a book that the domain of tan x was {(2n+1)π/2 , n∈I}

The set you wrote in post #1 is not the defined values of the function. The range of the tangent function (set of all output values) is all real numbers. That set in post #1 lists (by a formula) all of the numbers that are
