I'm attempting to draw the following two circuits up in NI Multisim 10, to attempt simulation and confirm my calculations.
However, I'm not sure how to represent the Vin and Vout sources. Also, multisim only seems to have amplifiers with power supplies, but all theory I read seems to draw the amplifiers without. Does that matter for a eventual simulation?
Also, ff there's any better software for the purpose than Multisim, then please tell.
Thanks.

Multisim does have ideal opamps, they can be found in the master database under Analog>Analog_Virtual_OPAMP_3T_VIRTUAL, but as Kortuk said, you should strongly consider using an opamp that forces you to include a power supply.
If you have a particular opamp that you know you will be using in a lab, you should see if you can find it in the multisim database. Multisim has very good models for how the opamps will actually act even more then just how you are powering them.
As for your question about Vin and Vout, in Multisim you can go to Simulate>Instruments and select what ever instrument you want to place. So you could put a function generator in for Vin and a Oscope for Vout.
