WebBessel functions and related functions. ¶. The functions in this section arise as solutions to various differential equations in physics, typically describing wavelike oscillatory behavior or a combination of oscillation and exponential decay or growth. Mathematically, they are special cases of the confluent hypergeometric functions \ (\,_0F_1 ... WebIf \(x_0\) is close to \(x_r\), then it can be proven that, in general, the Newton-Raphson method converges to \(x_r\) much faster than the bisection method. However since \(x_r\) is initially unknown, there is no way to know if the initial guess is close enough to the root to get this behavior unless some special information about the function is known a priori …
