Problems (1)–(3) illustrate an efficient method to derive differential equations. in general R sin(θ) cos(ωt), y = R sin(θ) sin(ωt), and the Lagrangian becomes. c) y = −106(y − sin(106t)) + cos(106t), y(0) = 1, t ∈ [0, 1].

Hence, for a differential equation of the type d 2 ydx 2 + p dydx + qy = f(x) where f(x) is a polynomial of degree n, Note: since we do not have sin(5x) or cos(5x) in the solution to the homogeneous equation (we have e −3x cos(5x) and e −3x sin(5x), which are different functions), our guess should work. 2018-05-29
