Multivariable calculus

Multivariable calculus, also known as multivariable analysis, is a branch of calculus that extends the concepts of single-variable calculus to functions of multiple variables. While single-variable calculus focuses on functions of one variable, such as \(f(x)\), multivariable calculus deals with functions of two or more variables, such as \(f(x, y)\) or \(g(x, y, z)\).
