A particle of mass m moves in a one-dimensional box of length I with the potential V = 00, I< 0, V = 0, 0 l. At a certain instant, say t = known to have the form 0, the wave function of this particle is p = V30/15 x (1 – x), 0< x < l, V = 0, otherwise. Write down an expression for (x, t > 0) as a series, and expressions for the coefficients in the series.
