Multiplicative inverse of polynomial
WebLets take. ax+by=1 ax + by = 1. This is a linear diophantine equation with two unknowns, which solution should be a multiple of \gcd (a,b) gcd(a,b) To calculate the modular inverse, the calculator uses this idea to find solutions to the Bezout identity using the EGCD: au+bv=\gcd (a,b) au + bv = gcd(a, b) Web9 dec. 2013 ยท We can give a simple routine to compute the multiplicative inverse of an element a -- Compute the inverse of a in the field Z/nZ. inverse' a n = let (s, t) = xgcd n a r = s * n + t * a in if r > 1 then Nothing else Just (if t < 0 then t + n else t)
