This course introduces higher order derivatives, Leibnitz theorem, for higher derivatives of the product of two functions. Series expansions of functions using Maclaurin’s theorem and Taylor’s theorem are discussed. Some applications of derivatives in finding maxima, minima, point of inflection etc are introduced. The concept of partial derivatives and its properties are also introduced. In integral calculus, certain reduction formulae are discussed. Application of integrals in finding plane area, surface area, arc length, and volume of solids of Revolution are introduced and double and triple integrals and some applications are also introduced.
