This article presents a new family iterative method for nding a multiple root of nonlinear equation with known multiplicity. Analytically it is showed using a Taylors expansion, geometric series, and binomial series ...
• (wahyu sari yeni, 2019-07-22)
This article discusses an iterative method for solving nonlinear equations, by com- bining Ababneh's iterative method of order four with Newton's iterative method. The method has eight order of convergence with three ...
• (2014-03-25)
In this artikel the combination of ratio estimators and ratio regression in simple random sampling using median and coefficient of skewness are discussed, which is a review and an expansion from the article J. Subramani ...
• (2013-03-13)
This paper discussed combining ratio estimators in simple random sampling using coefficient regression, coefficient kurtosis, coefficient variance suggested by Kadilar and Cingi . These estimators are biased there for ...
• (2014-03-25)
Estimators discussedare combination of ratio estimatorsin ranked set sampling using coefficient of variation and coefficient of kurtosis. Each estimator is biased estimatorand the mean square errors ...
• (2014-03-25)
Three estimators discussed in this paper are the Exponential Proportions Ratio Estimator, The Product Estimator Exponential Proportion, and The Combination-Product Ratio Exponential Proportions Estimator on simple random ...
• (2014-03-25)
This paper discusses the proof of the concurrent from Gergonne point. The Gergonne point of a triangle is the point at which the three lines from vertices to the points of tangency between the incircle and the sides of ...
• (2013-07-23)
This article discusses an equation to find an option pricing model, known as Black- Scholes equation. Black-Scholes equation is constructed with the concept of capital asset pricing model. Capital asset pricing model is ...
• (2014-03-25)
This paper discussed about three the ratio-product estimators for mean population in the stratified random sampling. It is combinations of ratio estimator and product estimator in stratified random sampling. This paper ...
• (2013-03-26)
Two types estimator for finite population mean in double sampling are ratio and product. These types are both proposed by Sukhatme and Srivastava so that four estimators are obtained. Four this estimator usually bias ...

We discuss prove the Erdős-Mordell Inequality. We will use signed distances from the sides of a triangle to prove that Erdős-Mordell Inequality not only to interior point of triangle, but also to exterior point of triangle. ...
• (2013-07-20)
We discuss a method to obtain an inverse of a nonsingular matrix, called Augmenta- tion and Reduction Method. The total computational cost of this method to obtain an inverse of a matrix is the same as those of Gauss-Jordan ...
• (2013-07-12)
Relation between two variables x and y are not always linear, but also non-linear. Scatter diagram from non-linear relationship will show a pattern of data points that can be approximated by an exponential curve. The ...
