# Supplementary mathematics/Laplace's equation

In mathematical calculations and analysis, Laplace's equation or Laplace's finite differential equation is a second-order partial differential equation that is denoted by the divergence symbol ▽ and is used in mathematics, physics, vantage point calculus, geometry, engineering, etc. This is a useful approach and function to determine an energy or electrical potential in free space or area, which is used in energy and high degrees compared to its structure, and for mathematics for sine and cosine signal waves, etc. in spherical coordinates. and cylindrical and Cartesian are used. Laplace's equation was derived to simplify calculations in physics and is named after the physicist Pierre Simon Laplace.
