👉 Derrises are a type of mathematical concept used in complex analysis. A derrive is an operation that takes a function and returns a new function, which can be thought of as "differing from" the original function by a constant factor. In simpler terms, if we have a function f(x) = ax^3 + bx^2 + cx + d, where a ≠ 0, then the derrive of f is defined as: f'(x) =
