What is another word for first derivative?
Pronunciation: [fˈɜːst dɪɹˈɪvətˌɪv] (IPA) 
The first derivative of a function, also known as the instantaneous rate of change, is a fundamental concept in calculus. This term can be referred to in different ways, such as the slope of the tangent line, the differential coefficient, or the gradient. Another synonym for the first derivative is the rate of change, which measures how quickly the function is changing at a specific point. It can also be called the derivative function or the derivative operator, as it takes the original function as input and outputs the rate of change. Understanding these synonyms can help clarify the concept and aid in solving complex calculus problems.
