WebApr 19, 2024 · No it's not right because not all non-removable singularities are essential. An essential singularity is a singularity that is not a pole of any order. Removable singularities are poles of order 0. So the point ##\pi/2## could be a pole of some finite order. That order cannot be greater than 7 since ##g(z):= f(z)(z-\pi/2)^7=\cos z## is holomorphic. WebIn the last lecture we saw that for 2nd order linear diﬀerential equations knowledge of one solution of the homogeneous equation suﬃces to provide the general solution to the inhomogeneous equation. In this lecture we study how to obtain systematically a solution of the homogeneous equation. 8. 1. Classiﬁcation of Singularities
