what is differential calculus and how is it used in practical there any problems (theory)in it

6 years ago


Answers : (1)


Dear sanket,

Differential calculus is a subfield of Calculas concerned with the study of how functions change when their inputs change. The primary object of study in differential calculus is the derivative. A closely related notion is the differential. The derivative of a function at a chosen input value describes the behavior of the function near that input value. For a real-valued function of a single real variable, the derivative at a point equals the slope of the tangent line to the graph of the function at that point. In general, the derivative of a function at a point determines the best linear approximation to the function at that point.
