Differentials is a specialized mathematical skill that involves finding the instantaneous rate of change in a function at a specific point. It is commonly used in calculus and related fields to solve problems related to optimization, motion, and change. The process involves calculating the limit of the difference quotient, which is the change in the output divided by the change in the input as the change in input approaches zero. This skill requires a solid understanding of calculus and mathematical concepts such as limits and derivatives.
