The purpose of this book is to study, investigate, analyse and to present stimulating and interesting findings of Ulam stability, Hyers-Ulam-Rassias stability, Ulam-GavrutaRassias stability, John Michael Rassias stability for different type of Reciprocal, Mixed and Quattordecic type functional equations under various spaces using direct method and fixed point method.Mathematics is the queen of Science. The functional equations are new and colorful feather in her cap and it decorate her crown as diamond. Though the modern study of functional equations originated 260 years ago, growth of this discipline happened in the last six decades. These developments are the sources of inspiration, attraction and influence to many mathematicians to bring more interesting results in the field of functional equations.
