Abstract

The purpose of this study was to analyze the influence of advertising and celebrity endorser of the brand image in increasing buying interest shampoo pentene in Pekanbaru community. The sample in this study were obtained using a non-probability sampling that respondents who meet the criteria of population where these samples do not have the same opportunities to choose from, with the sample criteria are respondents who use Pantene shampoo products and pernha see the ad. By using the formula according to Rao Purba, obtained a total sample of 96 people. Methods of data analysis using path analysis with SPSS 21. The results showed that the variables of advertising, celebrity endorser positive and significant impact on the image of Pantene shampoo brand in Pekanbaru. Then the ad variables celebrity endorser brand image positive and significant impact on buying interest Pantene shampoo in Pekanbaru. Based on the results of the analysis showed that the path celebrity endorser advertising variables affect the buying interest with the brand's image as a mediating variable in Pantene Shampoo advertising in Pekanbaru. It is expected that the company can continue to increase the rent, the company must continue to create new versions of the ads, giving rise to a new interest because of television viewers are getting bored with the same ad.

Abstract

This article discusses the extension of the pro duct integration rules which is a modification of the generalized Euler-Maclaurin summation formula using a partition of the trap ezoidal metho d. Analytically, it is showed that this metho d has an error of O(1/n 2). Furthermore, computational results show that the method is superior to the comparison methods by looking into the error value obtained.

Abstract

This article discusses the solution of nonhomogeneous linear partial differential equa-tions of first order and homogeneous nonlinear partial differential equations of second order using Adomian decomposition method. The obtained solution is of the form series. In the series solution of nonhomogeneous linear partial differential equations of the first order appears noise terms phenomenon, which is the same terms but with opposite sign, so that the solution obtained is a finite series.

Abstract

We discuss a family of iterative methods derived by giving a weight function recur-sively to the corrector of Newton’s method, which is a review of article of Herceg and Herceg publised on [Applied Mathematics and Computation, 87 (2010), 2533–2541]. Weighting with a specific index produces Super-Halley’s method. Analytically it is shown that the order of the convergence of the method is three. Furthermore, this iteration method requires four function evaluations per iteration, so its efficiency index is 1.316. Then, computational tests show that the discussed method is better than Newton’s method, and does not have significant differences with Super Halley’s method in terms of error produced.

Abstract

We discuss the modification of Newton’s method, which is a Predictor and Corrector method, to solve a nonlinear equation. Using a series based on the equation √ error of the method, we show that the order of convergence of the method is 1 + 2 and for each iteration, it requires two function evaluations, so the efficiency index of the method is 2.4142. To see the advantages of the proposed method, we compare the method with some known iterative methods using four test functions by varying an initial guess.

Abstract

This article discusses the analysis of the global convergence of Chebyshev method through the geometric interpretation of how to derive its formula using the parabolic equation. The results of the analysis are posed in the theorems, which state hypotheses criteria when the Chebyshev method converges globally for any initial guess at some intervals. For comparison, the hypotheses criteria when the Euler method and Halley iteration convergen globally are also discussed. In comparing these methods through the computations, we look into the fulfillment of the hypotheses criteria of the theorems for each method and the number of iterations required to obtain the estimated roots.
