[ILUG] Problems with Electronic voting (Dail questions)

dear sir/madam,
I've got a problemand i would be gratefullif you could help me with a 
solution.

**It's an ANTILOG AMPLIFIER(using two LF411 amp and two diode's 2N3904), 
The circuit generates an ouput voltagr proportional to the atilog of the 
input voltage. It's useful for computation.

1, Perform DC sweep of Vin from 0 to +5v and examine the the variation 
in Vout?

2, Assess how well the circuit perfoms the antilog functions(i.e.how 
accurate is it?)?

3, replace the op amps with UA741s and repeat question 1, and 2?
