 5 When solving an ODE using power series method, Why do we need to expand the solution around the singular point? 2 Asymptotic expansion of $\ln\left(\frac{x+a}{x-a}\right)$ in form of $\sum\limits_{n=0}^\infty a_n \left(\frac{1}{x}\right)^n$? 1 How many samples are required to estimate the frequency of occurrence of an output (out of 8 different outputs)?
