👉 Curtation is a mathematical concept in calculus that describes the rate at which a function changes with respect to its input. It measures how quickly the value of the function changes as it approaches a certain point, and can be used to understand the behavior of a function near a critical point. In other words, curtation represents the derivative of the function with respect to its input, or the rate at which the function is changing when the input is close to zero. It is useful in many applications where
