1. As an example, there are rational biquadratic and octic reciprocity laws. 2. This table collects 202 of the 331 invariants of ternary biquadratic forms. 3. Your right it is similar to a Biquadratic function. 4. Gauss published two monographs on biquadratic reciprocity. 5. SID's audio filter is modeled as an actual two-integrator-loop biquadratic filter. 6. This was by a'twisting'argument, implicitly about the L-function of biquadratic fields. 7. In the first one ( 1828 ) he proved Euler's conjecture about the biquadratic character of 2. 8. Biquadratic fields are the simplest examples of abelian extensions of "'Q "'that are not cyclic extensions.9. In the second one ( 1832 ) he stated the biquadratic reciprocity law for the Gaussian integers and proved the supplementary formulas. 10. For a memoir on " Certain cubic and biquadratic problems " the Royal Academy of Sciences of Berlin awarded him the Steiner prize.
