Abstract: The Plane cubie Systems given in literature [1], whieh possess quadratically algebraic limit cycle, is examined in the paper. Existence of quadratically algebraic limit cycle is here resolred, Existenec of many limit cycles studied, and the uniqueness of limit cycle proved, An example of the system possessing five limit cycles is finally given.
