    Not really. You loose a lot of accuracy because of the diode drops
    \ R1
    Vin -!<--+
    +-------- Vx
    \ R2

    i cant seem to understand the circuit...where do i connect the
    positive and negative terminal of the op-amp to this circuit...and

    You make a mirror image along the horz line.

    R1 and R2 are much lower values than R3 and R4
