What does differentiating mean?
"Differentiating" is the present participle and gerund of the verb "differentiate," which means to recognize or establish what distinguishes one thing from another. It is widely used in contexts ranging from science and business to everyday perception: a biologist may speak of differentiating two similar species, while a company highlights its differentiating features to stand out from competitors. The word carries a neutral, often analytical connotation, suggesting careful observation rather than judgment. In mathematics, differentiating has a precise technical meaning — computing the derivative of a function, a foundational operation in calculus introduced by Newton and Leibniz in the seventeenth century. Because the word spans both everyday discrimination between options and rigorous mathematical procedure, its meaning is usually clarified by context. It typically pairs with prepositions like "between" or "from" in general usage.
Recognizing or showing how two or more things are distinct from each other.
"The twins were so alike that even their mother had trouble differentiating their voices over the phone."
Usually followed by "between" or by two objects joined with "and" or "from."
Setting something apart by giving it distinctive characteristics.
"The brand succeeded by differentiating its product through superior customer service."
In mathematics, computing the derivative of a function.
"Differentiating both sides of the equation yields the rate of change directly."
Strictly technical register; the object is always the function being differentiated.
The action or process of distinguishing between things.
"Careful differentiating of symptoms is essential for an accurate diagnosis."
Every calculus student's rite of passage — differentiating is the same word whether you're telling twins apart on sight or taking the derivative of a curve.

Etymology of differentiating
"Differentiating" derives from the Medieval Latin verb "differentiatus," the past participle of "differentiare" meaning "to distinguish," itself built from Latin "differentia" (difference), from "differens," the present participle of "differre" — "to carry apart, differ." The root combines "dis-" (apart) with "ferre" (to carry). English adopted "differentiate" in the mid-nineteenth century, and the mathematical sense arose around the same period with the development of calculus terminology. It shares this Latin root with words such as "different," "difference," and "indifferent."
