Domain Of Function Y Tan X

Find the domain and range y tan x y tan x y tan x set the argument in tan x tan x equal to π 2 πn π 2 π n to find where the expression is undefined.

Domain of function y tan x. The domain is all values of x x that make the expression defined. The range of the tangent function is all real numbers. The graph of the secant function looks like this.

X π 2 πn x π 2 π n for any integer n n. The domain of the function y tan x is all real numbers except the values where cos x is equal to 0 that is the values π 2 π n for all integers n.
