Assignment:
a) Sketch the periodic function y=ex, -2< x <2 and y(x)=y(x+4) for values of x from -6 to 6. State the period and whether the function is odd even or neither.
b) give the Fourier series for the odd periodic extension of: y=ex, 0< x <2
c) Confirm Dirichlets theorem on both types of discontinuity
