DIFFERENTIAL CALCULUS

(ii) The derivative of y = f(x) w.r.t. x is also denoted by y’ or y1 or Dy or (iii) By the above definition, derivative of f(x) at x = c is. Provided this limit exists finitely and it is denoted by f’(c). Example: Consider the function f(x) = x2 . By definition = = 2x. Thus derivative of f(x) exists for all values of x … ................
