 p - prime r - integer

Description

 • Important: The numtheory[rootsunity] command has been deprecated.  Use the superseding command NumberTheory[RootsOfUnity] instead.
 • This function will calculate all the pth roots of unity mod r and return the result as an expression sequence.
 • The order, p, of the root must be prime.
 • Note that there will always be at least the root 1.
 • The command with(numtheory,rootsunity) allows the use of the abbreviated form of this command.
