PROJECTION IN GEOLOGY INTRODUCTION The term projection is used in two main contexts in geology: 1. Map Projection – the method of representing the curved surface of the Earth on a flat map. 2. Structural Projection – the method of representing three-dimensional geological data (such as planes and lines) on a two-dimensional diagram for analysis. > Both forms of projection are essential in geology because the Earth and geological structures exist in three dimensions, while maps, diagrams, and fie

When both the base and the variable are exponents, the usual elementary function we know so far may not be enough to solve this kind of equation. Thanks to Johann Heinrich Lambert and Leonard Euler for giving this Lambert W relation. #math | Math Avenue : Learn Math By Examples
