Content
Differential Coefficient of a Function
The study of the rates of change of variables with respect to other variables has led to the emergence of an important branch of mathematics called differential calculus.
Now suppose
, then a little change in y
will also lead to a little change in x
therefore,




Thus

Hence the
read as “dee
dee x” is called the differential coefficient or derivative of y with respect to x. other notations equivalent to
are
read as f…
