Return to Table of Content   Successive Differentiation Let   be a function of   the derivative or Differential coefficient of   w.r.t.   is denoted by Where   Similarly the second order derivative of y w.r.t. x is defined as Similarly we get nth derivative or Differential coefficient of   w.r.t.   and is denoted by   Application: 1.     Series expansion of a function like Taylor’s and McLaurin's series expansion. 2. Solution of ordinary and partial differential equations. Ex. Using Taylor’s Series Example 1: Find the nth derivative of Solution: differentiating y w.r.t. x we get,           …….......(1) Differentiating again w.r.t. x, we get …….......(2) Similarly differentiating successively, we get              …….......(3) .......(4) …   …   …   …   … ...
