👉 In mathematics, a "dervish" is a term used to describe an object that is continuously changing in shape or size. This concept is often used in the context of differential equations, where it represents a function whose derivative with respect to time measures its rate of change. For instance, consider the function f(x) = 2x^3 - x^2 + 4x - 1. If we differentiate this function with respect to x, we obtain: f'(x)
