Product description
1. Solve a linear differential equation using the operator method
αẍ + βẋ + γx = f(t), x(t0) = A, ẋ(t0) = B
The function f(t) and values of coefficients α, β, γ, t0, x(t0), ẋ(t0) are taken from the table. 16.4
1.9. α = 1, β = 1, γ = 0, f(t) = −2t, t0 = 2, x(t0) = 2, ẋ(t0) = −2
1.9. ẍ + ẋ = −2t, x(2) = 2, ẋ(2) = −2
2. Solve the system of linear differential equations by the operator method
Table of functions f1(t), f2(t) and values ak, bk, ck, dk (k=1, 2), A, B, x(0), y(0). 16.5
2.9. a1 = 1, b1 = 2, c1 = 2, d1 = 0, f1(t) = cost, a2 = 1, b2 = 1, c2 = −1, d2 = 0, f2(t) = 0, x(0 ) = 0, y(0)=0
