Analytical method, also known as analytical method, is a method to solve mathematical models by using analytical expressions.

definition

In mathematics, the method of expressing a function or any mathematical object with analytic expressions is called analytic method.

Analytic geometry includes two parts: plane analytic geometry and solid analytic geometry. Plane analytic geometry establishes one-to-one correspondence between points and real number pairs, and one-to-one correspondence between curves and equations through plane rectangular coordinate system, and uses analytical formulas to study geometric problems numerically. /kloc-since the 0/7th century, due to the development of navigation, astronomy, mechanics, economy, military and production, as well as the rapid development of elementary geometry and elementary algebra, analytical geometry has been established and widely used in various branches of mathematics. Before analytic geometry was founded, geometry and algebra were two independent branches. The establishment of analytic geometry has truly realized the combination of geometric method and algebraic method for the first time, and unified shape and number, which is a major breakthrough in the history of mathematical development. As the first decisive step in the development of variable mathematics, the establishment of analytic geometry plays an inestimable role in the birth of calculus.
