UNIT IFOURIER SERIES
PART A1. Explain periodic function with two examples.2. State Dirichlets condition
3. To which value,the half range sine series corresponding tof(x)x2 expressed in theinterval (0,5)converges at x=5?
4. If f(x) = eax is expanded as a Fourier series in (0,2) what is the value ofbn . 5.Doesf(x) = tan x posses a Fourier expansion?6.Obtain the value of a0 in the Fourier expansion of f(x) = 1 cosx in (0,2) 7.In the
