Abstract

Telegraph is a machine for sending and receiving messages remotely. Telegraph according to Zauderer can be modeled or expressed in mathematical language, namely the telegraph equation. Kirchoff I's Law deals with currents and Kirchoff II's Law is the basis for analyzing all electrical circuits. The purpose of this research is to apply Kirchoff's Law to obtain the telegraphic equation. The stages in research include: determining the equivalent circuits, making assumptions, applying Kirchoff's Laws I and II to the equivalent circuits, and forming telegraphic equations. The results of this study are to obtain a telegraphic equation which is a partial differential equation with general forms

Abstract

The linear transformation is a function relating the vector ke . If , then the transformation is called a linear operator. Several examples of linear operators have been introduced since SMA such as reflexive, rotation, compression and expansion and shear. Apart from being introduced in SMA, these linear operators were also introduced to the linear algebra course. Linear transformations studied at the university level include linear transformation in finite dimension vector spaces . The discussion includes how to determine the standard matrix for reflexive linear transformations, rotation, compression and expansion and given shear. Through the column vectors of reflexive, rotation, compression and expansion and shear, a standard matrix of 2x2 size is formed for the corresponding linear transformation. however, in this study, the authors studied linear transformations in dimensioned vector spaces . The results of this study are if known is a vector space with finite and the standard matrix for reflexivity, rotation, expansion, compression and shear is obtained. Each of these linear transformations is performed on x-axis, y-axis and z-axis on to get column vectors. The column vectors as a result of the linear transformation at form the standard matrix for the corresponding linear transformation in the vector space. The standard matrix for linear transformations in the vector space is obtained by determining reflexivity, rotation, expansion, compression and shear. The process of obtaining a standard matrix for linear transformation is carried out by rewriting the standard basis, determining the column vectors, and rearranging them as the standard matrix for each linear transformation in the vector space
