We are here basically concerned with the form f(z) = a(0) + a(1)z + a(2)z(2) +.... f(z) is an element of A, f(z) = z + Sigma(infinity)(n=2)a(n)z(n) will be an analytic function in the open unit disc U = {z : |z| < 1,z is an element of C} normalized by f(0) = 0, f '(0) = 1. In this work, starlike functions and close-to-convex functions with order 1/4 have been studied according to the exact analytic requirements.en10.2298/TSCI22S2639Yinfo:eu-repo/semantics/openAccessanalytic functionunivalent functionclose to convex functionstarlike functionArticle26S639S645Q4WOS:0009212317000152-s2.0-85148213374Q3
