Mathematics-II Paper Code BE-301 Faculty: Sonendra Gupta Mobile: 9893455006 UNIT–1 1. a) What is periodic function, gave an example of periodic function. 2 Solution: A function f (x) is said to be periodic if there exist a least positive integer T such that Suppose f ( x ) f ( x T ) f ( x 2T ) ...... f ( x nT ) , n I Where T is called period of f (x). Example: sin x, cos x of period 2 while period of tan x is b) What are the Dirichlet’s conditions for a Fourier series expansion? 2 Solution: Suppose f (x) is any finite function defined in (–L, L), then the Fourier series of f (x) is exists only if the following conditions are satisfied: (i). f (x) is periodic i.e. f (x) = f (x + 2L), where 2L is the period of f (x) (ii). f (x) and its integral are finite and single valued. (iii). f (x) has a finite number of discontinuities. (iv). f (x) has a finite number of maxima and minima. These conditions are known as Dirichlet’s conditions. c)
