Technique of research of accuracy of formulas for calculation rectangular coordinates of the projection of Gauss - Krueger on geodetic coordinates

The technique of research of accuracy of formulas by creation of the rest of a row by means of infinitesimal sizes of one order of a malost is offered. The analysis of algorithms on accuracy for calculation of rectangular coordinates x, by y of a projection of Gauss - Krueger for the meridian zones increased on longitude is made.
