How do you find the period of tan x?

Answer 1

James Adkins

The period of #tan x# is #pi#.

You can see it on the graph: graph{tanx [-10, 10, -5, 5]}

Example: tan #pi/4# and #tan (pi/4 + pi)# have the same value (#1#).

The period of the tangent function ( \tan(x) ) is π. This means that the graph of ( \tan(x) ) repeats itself every π units along the x-axis.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
