FAQ

Frequently Asked Questions

It is named after the German mathematician and astronomer Friedrich Wilhelm Bessel (1784–1846).

No, it is a highly specialised mathematical tool used in theoretical and applied science and engineering.

It is typically an approximation or series expansion method, though it can yield exact solutions in the form of infinite series (Bessel functions).

Bessel functions are canonical solutions y(x) to Bessel's differential equation. The 'Bessel method' often involves applying or approximating these functions.

A mathematical technique for approximating the roots of equations, particularly used for solving transcendental equations.

Bessel method is usually highly technical/specialist in register.

Bessel method: in British English it is pronounced /ˈbɛs.əl ˈmɛθ.əd/, and in American English it is pronounced /ˈbɛs.əl ˈmɛθ.əd/. Tap the audio buttons above to hear it.
