Question 19
dr-y = cost, dry-dr + x = e, mia =-kix + k2(y-x), dt d2 dt dy dx dt equation to a first-order linear system. 16. y" + 2,y, + y = cost. 17. y"' +ay' +by- F(t), a, b constants. where α, α2.03, and α4 are constants. Convert this problem into an initial-value problem for an equiva- lent first-order linear system. (You must give the ap- propriate initial conditions in the new variables.) 20. Solve the initial-value problem: x,--(tan t)x1 + 3 cos2 t, X2 = X1 + (tan t)X2 + 2 sin t, 19. The initial-value problem that governs the behavior of Xi(0)=4, x2(0)=0. a coupled spring-mass system is (see the introduction to Chapter 7)
