equations

An equation is a mathematical equality between two expressions containing one or more variables, called unknowns.

Absolute value equations are equations in which the variable \( x \) appears inside an absolute value expression.

Logarithmic equations are equations in which the unknown appears inside a logarithm. To solve them, it is crucial to understand the properties of logarithms and how these can be applied to isolate and determine the value of the unknown.

Homogeneous trigonometric equations are equations in which all terms involve trigonometric functions, such as sine and cosine, raised to the same degree.

Trigonometric equations are equations in which the unknown appears as the argument of trigonometric functions. There are various types of such equations, each with its corresponding solution method.
