Learn how to eliminate the parameter in a parametric equation. A parametric equation is a set of equations that express a set of quantities as explicit functions of a number of independent variables, ...

I make short, to-the-point online math tutorials. I struggled with math growing up and have been able to use those experiences to help students improve in math through practical applications and tips.

Let's explore the process of graphing equations within a rectangular coordinate system, also known as the Cartesian coordinate system. Understanding how to visualize equations as graphs is fundamental ...

The portly, balding sculptor-turned-architect must have drawn a few curious gazes as he set up a complicated painting apparatus in the corner of a Renaissance-era piazza. He planted his instrument, ...

Abstract: This paper presents a new steady-state estimator based on the Cartesian coordinate formulation of nodal and line flow equations and minimization of weighted least squares (WLS) of the ...

Polar coordinates are an alternative coordinate system to the commonly used Cartesian (rectangular) coordinates. They are particularly useful in situations where data can be more easily represented ...
