1. Find a particular solution of a linear homogeneous differential equation.
1.7 yIV + 2y-2y- y = 0, y (0) = 0, y (0) = 0, y (0) = 0, y (0) = 8
2. Solve the system of differential equations in two ways: a) information to higher order differential equations; b) using a characteristic equation.
2.7 x ´= 6x-y, y´ = 3x + 2y
3. Solve the differential equation by variation of arbitrary constants.
3.7 y + 2y + 2y = e-x / cosx
4. Solve the following problems.
4.7 Write the equation of curves for which the sum of the other two sides of the triangle formed by the tangent, perpendicular from the tangent point on the x-axis and the x-axis, is constant, equal to a.
