Problem Session for MTH G131: 11/16/06 1). Use the Laplace transform to solve the initial value problems: y 00 + 3 y 0 + 2 y = 0 , y (0) = 1 , y 0 (0) = 0 y 00 - 2 y 0 + 2 y = e - t , y (0) = 0 , y 0 (0) = 1 2). Define f ( t ) = ± (sin t ) /t, for t 6 = 0 1 for t = 0 Find the Taylor series for f about t = 0. Assuming that the Laplace transform of this function can be computed term by term, show that L [ f ] = arctan ² 1 s ³ 3). Suppose that L [ f ] = F ( s ), show that for constants
