WebIn algebra, the rational root theorem (or rational root test, rational zero theorem, rational zero test or p/q theorem) states a constraint on rational solutions of a polynomial … WebSpecifically, one may define the principal value of the argument separately on the two half-planes x > 0 and x < 0 (separated into two quadrants if one wishes a branch cut on the negative x -axis), y > 0, y < 0, and then patch together. A compact expression with 4 overlapping half-planes is It's also possible to use arccotangent for the definition:
