I have two functions $f1$ and $f2$.
I know I can plot them on the same graph doing this :
Plot[{f1[x],f2[x]},{x,xmin,xmax}]
But how can I choose one range for $f1$ and another for $f2$ such that $xmin^1 \neq xmin^2$ for example ?
Remark : I am looking for a very simple code, the linked proposed seems a little too "complicated". But the comment proposed answered my question
EDIT :
The following code just plot one curve for me :
Show[Plot[Sin[\[CapitalDelta]I], {\[CapitalDelta]I, -2, 0}],
Plot[Cos[\[CapitalDelta]I], {\[CapitalDelta]I, -1, 0}]]
I only see the Sin and not the Cos here.
