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
