Representing Geometric Objects/Fields in Coordinate Systems
Geometric Objects like Curves and Surfaces are represented mathematically through the following
Scalar Coordinate Equations: These are some Scalar Function Equations that a particular Geometric Object satisfies. The Variables in these Scalar Function Equations are Coordinates Axes of the Coordinate System in which the Geometric Object is represented.
Parametric Equations / Position Vector Functions: In this representation the Cartesian Coordinates \(x, y, z\) etc. are themselves given in terms of Scalar Functions of 1 or More Parameters/Variables.
The value of the \(x,y,z\) thus obtained form the Components of Position Vector of Points on the Geometric Object.
Vector Equations: These are some Vector Equations that a particular Geometric Object satisfies.
Each of the above representation can have Various Types Depending on the Actual Geometric Object.
Data Distributions / Fields are represented mathematically through the following
Scalar Coordinate Expressions: These are Scalar Function Expressions that represent Fields. The Variables in these Scalar Function Expressions are Coordinates Axes of the Coordinate System in which the Field is represented.
Vector Functions: These are Vector Function Expressions that represent Fields. Each Component of the Vector Function is a Scalar Function Expression. The Variables in these Scalar Function Expressions are Coordinates Axes of the Coordinate System in which the Field is represented.
