Abstract: The paper put forward pseudo linear transformation method for solving nonlinear algebraic equations. Based on the new method, the paper discusses an inverse mapping of rational parameter surface, also, the implicit equation of the parametric equation is obtained. The presented method provides a new way for solving the problem involving nonlinear algebraic equation in many fields such as geometric theorem machine proven, CAD, forward and inverse kinematics of robots.
