please provide answers

1) Solve this differential equations by the method of undetermined coefficients; y" +y' + 4y = 2 sinht2. (4 points) Determine a suitable form for Y(f) if the method of undetermined coefficients is to be used. Do NOT evaluate the constants. y" + 3y' + 2y = e" (t? + 1) sin (2t) + 3e 'cost + 46'
