A plate in the form of a sector of a circle of radius a has a
central angle beta, as shown in Fig. 2-30. If the circular part is
maintained at temperature f(0), 0 < theta < beta, while the
bounding radii are maintained at temperature zero, find the
steady-state temperature everywhere in the sector.
