👉 The term "artlet" is a mathematical concept that refers to a function whose derivative at a point (the slope of its tangent line) equals 1. It's often used in calculus and analysis, particularly in optimization problems where one seeks points on curves or surfaces where the function has a maximum value. In simple terms, an artlet is a curve such that if you take any point on it and move it along a straight line, the result will be another point on the same curve.
