Summary: We find estimates on the coefficients \(|a_2|\) and \(|a_3|\) for functions in the function class \(B(\lambda,\mu,\phi)\). The results presented in this paper improve or generalize the recent work of \textit{B. S. Keerthi} and \textit{B. Raja} [Theor. Math. Appl. 3, No. 1, 1--10 (2013; Zbl 1302.30016)].
