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.
