Unformatted text preview: λ =0,1,2,3,4 with Mathematica. Which functions are odd and even? How are the two kinds different? Does anything “special” happen at x=0 in some cases? (7) What is the general solution to the following ODE (solve it by hand using the results from our in class derivations, i.e., don’t do through the derivation again)?
