In algebra, the distinction between polynomial and transcendental equations lies in the nature of the functions used to define them.

A polynomial equation is formed by setting a polynomial equal to zero. Polynomials are expressions consisting of variables and coefficients, where the variables are raised to non-negative integer powers. These equations can be analyzed completely using the methods of algebra and calculus.1

In contrast, a transcendental equation is an equation that contains transcendental functions of the unknowns. These functions are non-algebraic and include exponential and trigonometric functions, such as ex or sinx. While polynomial equations involve only basic arithmetic operations (addition, multiplication, and non-negative integer exponentiation), transcendental equations involve functions that cannot be expressed as a finite sequence of these algebraic operations. Historically, curves defined by transcendental equations were often referred to as mechanical, whereas those defined by polynomials were considered geometric.2314
