## What is meant by analytical calculation methods?

The term "analytical methods" refers to mathematical techniques used for solving mathematical problems exactly through symbolic manipulations and closed-form expressions. These methods allow for precise and exact solutions, as opposed to numerical methods, which provide approximate solutions.

Typical software functions in the area of "analytical methods":

- Symbolic Computations: Performing calculations with variables and expressions without numerical evaluation.
- Equation Solvers: Solving algebraic, differential, and integral equations in closed form.
- Symbolic Differentiation: Calculating derivatives of functions symbolically.
- Symbolic Integration: Determining integrals analytically, when possible.
- Series Expansions: Representing functions as series, such as Taylor or Fourier series.
- Transformations: Performing mathematical transformations, such as Laplace and Fourier transforms.
- Formula Simplification: Simplifying complex mathematical expressions.
- Symbolic Matrix Operations: Calculating determinants, inverses, and eigenvalues of matrices in symbolic form.
