Answer:
It means that tan x will be defined for all values except the values that will make cos x = 0, because a fraction with denominator 0 is not defined. Hence, for these values, tan x is not defined. So, the domain of f(x) = tan x will be R – ( 2 n + 1 ) π 2. and the range will be set of all real numbers, R.
