differential coefficient

Thus he differentiated with respect to x and equated the differential coefficient to zero.

The only way of 544 finding out whether this condition is satisfied or not is to attempt to form the differential coefficient.

When this condition is satisfied y is a function of x which has a differential coefficient.

It appears that we can always find the area A if we know a function F(x) which has ƒ(x) as its differential coefficient.

Sometimes the symbols d or ∂ are dropped, and the partial differential coefficient is denoted by ux or ƒx.
