Hi,

I want to create a tangent function.

I know that you can create tan(x) but how can you create the tangent function when the solutions are only:

x in [0.19740;0.91510[ union [3.3390;4.0567 ?

 

Another explanation:

How you can graphically show the valid values of x in this inequality?

                  0.2 ≤ tan x < 1.3
Best regards
