# Euler-Cauchy Equation

Consider the differential equation: r^2*R"+r*R'-R=0

a) Find all values of n for which the function R=r^n is a solution to the differential equation. Do this by substituting {the solution into the DE and seeing which values of n will make the equation true.

b) Solve the initial-value problem (IVP) with R(1)=2 and R'(1)=0.
