Consider the following statements. (i) Spring/mass systems and Series Circuit systems we covered are examples of linear dynamical systems in which each mathematical model is a second-order constant coefficient ODE along with initial conditions at a specific time. (ii) The following is an example of a piece-wise continuous function f (x) = { x x ∈ Q 0 x ∈ R \ Q (iii) It is unclear whether series solutions to ODEs even exist, and knowing about series solutions to...
Consider the following statements. (i) The Laplace Transform of 11tet2 cos(et2) is well-defined for some values of s. (ii) The Laplace Transform is an integral transform that turns the problem of solving constant coefficient ODEs into an algebraic problem. This transform is particularly useful when it comes to studying problems arising in applications where the forcing function in the ODE is piece-wise continuous but not necessarily continuous, or when it comes to studying some Volterra equations and integro-differential equations. (iii)...
Consider the following statements. (i) Given a second-order linear ODE, the method of variation of parameters gives a particular solution in terms of an integral provided y1 and y2 can be found. (ii) The Laplace Transform is an integral transform that turns the problem of solving constant coefficient ODEs into an algebraic problem. This transform is particularly useful when it comes to studying problems arising in applications where the forcing function in the ODE is piece-wise continuous but not necessarily...
Problem #2: Consider the following statements. [6 marks) (1) The particular solution of the ODE)" - 6y' + 9y = 5e3x is given by yp = Cre3x where C is an undetermined constant. (ii) The procedure of finding series solutions to a homogeneous linear second-order ODEs could be accurately described as the "method of undetermined series coefficients". (iii) Most of the material in Lecture Notes from Week 3 to Week 5, inclusive, can be extended or generalized to higher-order ODES...
Consider the following statements. (i) A Taylor series is a power series that gives the expansion of a function around a point a. Convergence of such series is fully understood by means of the ratio test. (ii) We must rethink what we mean by solving y′′ + y′ − y = { cos(x + 42) x ≠ 1 0 x = 1 before trying to compute a solution defined on an interval containing x = 1. (iii) Most of the...
IGNORE (i) (ii) The procedure of finding series solutions to a homogeneous linear second-order ODEs could be accurately described as the “method of undetermined series coefficients”. (iii) The underlying idea behind the method of undetermined coefficients is a conjecture about the form of a particular solution that is motivated by the right-hand side of the equation. The method of undetermined coefficients is limited to second-order linear ODEs with constant coefficients and the right-hand side of the ODE cannot be an...
Problem 1 Consider two first order low-pass systems connected in parallel: -2u The objective is to determine a second order ODE describing the variable y by manipulating the differential equations (no transfer function techniques are allowed). Answer the following series of questions: 1. (2 points) Write the variable y in terms of i and 2 2. (6 points) Determine the relationship between y, j, and z1, z2 and u. Write your final expression in a matrix-vector format: ? 01 ??...
