The purpose of this paper is present a brief survey of know on estimates the rate for best approximation of unbounded functions by suitable trigonometric polynomials of one variable in weighted space . Moreover we studied   concerning the degree of best trigonometric approximation of  with  non-integer in .


Keywords: Unbounded functions, trigonometric polynomials, weight space.
