Product description

• 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
