👉 In mathematics, a Bourreau number is a positive integer that represents an upper bound for the value of a certain function in terms of its derivative. It can be defined as: \[ \text{Bourreau} = \lim_{h\to0}\frac{\int_a^bf(x)dx - h}{f'(x)} \] where \(a\) and \(b\) are constants, and \(f\) is a differentiable function. For example, if we have the function
