Unformatted text preview: Classwork Twenty-Seven: NAME: Find the singular points, determine the regularity and give indicial equations for the regular points: x 2 ( x- 1) y 00 + ( x- 2) y + (2 cos x ) y = 0 Classwork Twenty-Six: NAME: Find the first 4 nonzero terms of a power series solution to y 00 = ( sin x ) y ; y (0) = 6; y (0) = 12 Classwork Twenty-Five: NAME: Use power series to find a solution to xy = ( x + 1) y . Find the first four nonzero terms, find a recurrence relation. Then try to find the general terms of the power series and a closed form for the solution, from the power series. HINT: a = 0. Classwork Twenty-Four: NAME: Find the Taylor polynomial P 4 for a solution to the differential equation y 00 = y + e x y ; y (0) = 1; y (0) = 2 . Classwork Twenty-Three: NAME: Find the transform Y ( s ) and the solution y ( t ) to the differential equation y 00 + 2 y + 5 y = g ( t ); y (0) = 0; y (0) = 2 Express Y ( s ) in terms of G ( s ) and use convolution to express y ( t ) in terms of g ( t )–write out the integral. Classwork Twenty-Two: NAME: Use convolution to find the inverse Laplace transform f ( t ) of F ( s ) = s ( s 2 +4) 2 . Classwork Twenty-One: NAME: Solve the differential equation y 00- 2 y- 3 y = 2 δ ( t- 1) with y (0) = 2 and y (0) = 2....
