WebBrentq Method¶. Brent’s method is a combination of bisection, secant and inverse quadratic interpolation. Like bisection, it is a ‘bracketed’ method (starts with points \((a,b)\) such that \(f(a)f(b)<0\).. Roughly speaking, the method begins by using the secant method to obtain a third point \(c\), then uses inverse quadratic interpolation to generate the next possible root.
