Question
Match the solution curve with one of the differential equations.
y" + 4y = 0
О у" + 2y' + у %3D 0
O y" + y = 0
O y" – 2y' – 3y = 0
О у" - 7y' + 12у %3D 0
y" + 2y' + 2y = 0
Explain your reasoning. (Assume that k, k1, and k2 are all positive.)
O The auxiliary equation should have a repeated negative root, so that the solution has the form cje-kx + c2xe¯kx.
The auxiliary equation should have a pair of complex roots a ± ßi where a < 0, so that the solution has the form e"x(c1 cos Bx + c2 sin Bx).
The differential equation should have the form y" +
k?y
= 0 where k = 1, so that the period of the solution is 2n.
