-
In calculus, the differential coefficient helps us understand how quickly a function changes at any given point.
-
To calculate the differential coefficient, find the derivative of the function at that specific value.
-

Synonyms

Morphology
The element 'differential' clearly signals a relation to derivatives and rates of change and 'coefficient' suggests a measured or numerical quantity, so a learner might infer this is a quantity associated with differentiation. However, the precise technical sense—that it denotes the derivative or instantaneous rate of change—is specialized and not fully predictable from the everyday meaning of 'coefficient', so subject-matter knowledge is needed.
Etymology
Differential coefficient comes from old math words: differential means a very small 'difference' and coefficient is a number that goes with something. So the phrase names the number that shows a tiny change of one thing compared to another — the 'instant rate of change'.
