Casio fx-7400G Plus Power GraphicEngineering Surveyor ProgramsRADIALIntroductionComputes the “Bearing & Distances” from a central point to any number of otherpoints. This program removes the need to keep re-entering the first set of coordinates.DiagramE1, N1Bearing & HzDistanceE2, N2Eo, No…….……E3, N3Input“From” co-ordinates:“To” co-ordinates:(Eo, No)(E1, N1) (E2, N2) (E3, N3) …….OutputBearing & Distances: (Eo, No) to (E1, N1)(Eo, No) to (E2, N2)(Eo, No) to (E3, N3) ……Page 22 of 38
