on the interval –n <x < T, where a >1 is real.

Recast the function f(x) from the previous problem as a (rational) function F(w)
of the complex variable w := eir, and extend F(w) to the entire complex plane.
a. Find and classify all singular points w eC of the function F(w).
b. Compute the (interior) Laurent series expansion of F(w) about the origin w = 0. What is
the radius of convergence for this series?
c. Use your result from part (b) to recompute the Fourier series expansion of f(x) from the
previous problem. Confirm that your result here agrees with the one you found there.

System that uses coordinates to uniquely determine the position of points. The most common coordinate system is the Cartesian system, where points are given by distance along a horizontal x-axis and vertical y-axis from the origin. A polar coordinate system locates a point by its direction relative to a reference direction and its distance from a given point. In three dimensions, it leads to cylindrical and spherical coordinates.
