For an electron in a box, the ground state energy E_1 = 2 ~\text{eV}E 1 =2 eV, For what transition would the energy difference be 5 E_15E 1 (ie. from what starting value of n_in i to what final value of n_fn f )?

(1 point) match the differential equations and their vector valued function solutions. you may wish to multiply at least one solution out fully, to make sure that you know how to do it. you can get the other answers quickly by process of elimination and just multiply out one row element.
