Solving for the values of x in a quadratic equation yields 2 values, called the root of the quadratic equation. Quadratic equations always yields 2 values as its roots, or answer. This rises from the fact that the formula to solve a quadratic equation is, x= -b ±√b2- 4ac/(2a) T...

Tau (τ) is the ratio of a circle’s circumference to its radius. This constant is equal to 2π, or roughly 6.28. Like pi, tau is an irrational number because it’s just pi times two.Many mathematical expressions use 2π, and using tau instead can help simplify your equations. For ...
Fq[idxq(i,j)] contains the coefficient of the quadratic monomial x_i*x_j, with i < j. The function idxq() is defined in fes.h Now, all these coefficients are indeed 0/1. The trick is that there are 32 equations, and that the code uses “bitslicing”. It uses a single array...
