I hope that I'm not disturbing you with a similar question again.
I just wanna make sure I am correct on this one.
______________________________________________
I have to find:
• Output Waveform
• $V_{AVG}$

Here's the circuit:

$V_o$ terminals are as usual.

$V_i=6sin(\omega t)$
_____________________________________________________

$V_i>2V$, D1 ON, D2 OFF, $V_o=3sin(wt)+1$
$V_i<-4V$, D1 OFF, D2 ON, $V_o=-4V$
$-4\leq V_i \geq 2V$, D1 OFF, D2 OFF, $V_o=V_i$

* $V_o$ waveform:

* $V_{AVG}$:

which gives as a result $V_{AVG}=-0.155847$
_________________________________________________________
Am i right ? Im not sure because this is the most complex waveform I solved.

I see that you found Mathematica, presumably on your school's network.

I solved the problem using the simpler method I demonstrated in the other thread. I get exactly the same result, so you're good to go.
