Here is my task:(adsbygoogle = window.adsbygoogle || []).push({});

Construct circuit ??? which uses power supplies +12V and -12V and gives output voltage:

where

Here is circuit:

I solved it using 4 opamps:

First opamp scales V3, second integrates V4, third sums the results of the prior two circuits and fourth inverts signs in sum (output of third opamp). Can this problem be solved using single opamp?
