"Originally presented as lectures, the theme of this volume is that one studies orthogonal polynomials and special functions not for their own sake, but to be able to use them to solve problems. The author presents problems suggested by the isometric embedding of projective spaces in other projective spaces, by the desire to construct large classes of univalent functions, by applications to quadrature problems, and theorems on the location of zeros of trigonometric polynomials. There are also applications to combinatorial problems, statistics, and physical problems."

"ABSTRAKTugas akhir ini membahas analisis jenis-jenis wavelet orthogonal dan biorthogonal untuk diterapkan dalarn bidang kompresi gambar. Tujuan dari analisis tersebut adalah untuk menentukan jenis wavelet yang paling sesuai clan berkinerja baik. Analisis yang dilak-ukan meliputi persebaran clan energi koefisien yang dilakukan pada transformasi wavelet maju yang diterapkan pada gambar-gambar tes non-standar dan gambar tes standar ""Lenna"". Juga dilakukan perhitungan waktu proses yang dibutuhkan dalam melakukan suatu transformasi wavelet maju dan transfonnasi wavelet balik serta nilai PSNR dan entropi yang diperoleh. Analisis ini dilakukan dengan bantuan model simulasi yang dibuat dalam lingkungan pemrograman Matlab 4.0.

"The first part of the book (basic methods) covers convergent and divergent series, Chebyshev expansions, numerical quadrature, and recurrence relations. Its focus is on the computation of special functions; however, it is suitable for general numerical courses. Pseudoalgorithms are given to help students write their own algorithms. In addition to these basic tools, the authors discuss other useful and efficient methods, such as methods for computing zeros of special functions, uniform asymptotic expansions, Pad approximations, and sequence transformations. The book also provides specific algorithms for computing several special functions (like Airy functions and parabolic cylinder functions, among others)."

"Pada tugas akhir ini dibahas mengenai penurunan formula eksplisit polinomial Chebyshev dengan menggunakan komposisi fungsi pembangkit dan suatu fungsi yang disebut composita. Composita diperlukan untuk mencari koefisien-koefisien dari hasil komposisi fungsi pembangkit. Kemudian, dari koefisien-koefisien tersebut diperoleh bentuk umum formula eksplisit polinomial Chebyshev. Formula eksplisit polinomial Chebyshev jenis pertama diturunkan menggunakan komposisi dari fungsi pembangkit F(x,t)=2xt-t^(2 ) dan G(t)=1/(1-t) yang dikalikan dengan (1-xt). Formula eksplisit dari polinomial Chebyshev jenis kedua diturunkan dengan menggunakan komposisi dari fungsi pembangkit F(x,t)=2xt-t^(2 ) dan G(t)=1/(1-t). Sedangkan Formula eksplisit polinomial Chebyshev jenis ketiga dan keempat berturut-turut diturunkan menggunakan komposisi dari fungsi pembangkit F(x,t)=2xt-t^(2 ) dan G(t)=1/(1-t) yang dikalikan dengan (1-t) dan (1+t).

In this skripsi, the way of deriving explicit formula of Chebyshev polynomials is carried out by using composition of generating functions and a function called composita. Composita is needed to find the coefficients of the composition of generating function. From the coefficients, the explicit formula of Chebyshev polynomials are obtained. Explicit formula of Chebyshev polynomials of the first kind is derived by multiplying (1-xt) to the composition of the generating function F(x,t)=2xt-t^(2 ) and G(t)=1/(1-t) . Explicit formula of Chebyshev polynomials of the second kind is derived by using the composition of the generating function F(x,t)=2xt-t^(2 ) and G(t)=1/(1-t). In addition, explicit formula of Chebyshev polynomials of the third kind is derived by multiplying (1-t) to the composition of the generating function F(x,t)=2xt-t^(2 ) and G(t)=1/(1-t) and fourth kind is derived by multiplying (1-t) to the composition of the generating function F(x,t)=2xt-t^(2 ) and G(t)=1/(1-t)."
