1. Find a particular solution of a linear homogeneous differential equation.
1.25 y + 2y + 9y + 18y = 0, y (0) = 1, y (0) = -3, y (0) = -9
2. Solve the system of differential equations in two ways: a) information to higher order differential equations; b) using a characteristic equation.
2.25 x ´= 5x + 8y, y´ = 3x + 3y
3. Solve the differential equation by variation of arbitrary constants.
3.25 y- y = e2xcos (ex)
4. Solve the following problems.
