1 Fundamental of Atrodynamic and Application 4 th Ed Conolidated Errata February 4, 08 Thi liting i an on-going document of correction and clarification encountered in the book. I appreciate any comment and quetion you find. I ue RHS for right hand ide when referring to equation and N/A for not applicable. You may reach me at: dvallado@agi.com or davallado@gmail.com. Change in equation are ometime indicated by circle. I have tried to indicate change that were preent in previou edition a I know many of you have thoe copie. For many correction in the nd edition, the firt and econd printing had identical page, unle otherwie noted with the firt printing page being in parenthee. The exact decription may differ, but it hould get you cloe enough. Page xiv, Algorithm : The cro reference hould ay pg 63, not 7.
