Engineering Equation Solver (Thai)

This document introduces the Engineering Equation Solver (EES) software. EES is a general purpose equation solver and modeling tool designed for engineering education. It allows users to solve systems of nonlinear equations without programming by using an implicit iterative solver. EES includes features such as built-in properties, functions, units support, and parametric studies. Tutorial examples are provided to demonstrate solving equations, formatting equations, and performing a parametric study to analyze the maximum distance traveled by a projectile.
