The biggest problem of the discrete analysis is the huge amount of cubic and quartic equations that should be calculated.
An exact analysis in the final balance is complicated because there is a need to calculate numerous cubic and quartic equations to find [u.
As a result, all cubic and quartic equations are transformed to quadratic equations.
Mathematics of the first year in high school includes: Sets, Real and Complex numbers, Discriminant, Cubic and Quartic Equations
