👉 In mathematics, a surlier is a function that is equal to its derivative. This means that if f(x) = g'(x), then f'(x) = g(x). In other words, the derivative of a function gives us the slope of the tangent line at any point on the curve. For example, consider the function f(x) = x^2 - 3. The derivative of this function is given by f'(x) = 2x. If we take the
