Hi, I have a question regarding partial fractions. One of my Math lecturers said that to find partial fraction, we are actually finding the singularity points. I don't understand what happens at a singularity point that allows us to decompose a function into the sum of two other functions. How does taking the limit of a function as it approaches a singularity point help us find the partial fractions. I've looked at graphs of functions to try and understand it, but I don't see it. I have been wondering this for a while now and some help would be very much appreciated! Thank you.
