(2) Convert the following fourth-order ODE to a system of (four) first order ODEs. y(4) + 3y" + 6y" – 9y - 12y = 0 System for (2):
Part B - Modelling and Solving First Order ODES Charlie decides to create a theoretical model of his riding velocity to test whether his watch is callibrated properly. To simplify the problem, Charlie decides to test the watch on flat ground. As a further simplification, Charlie decides to start their trial at 10 m/s and then let the bike coast (aka no external force). 1. Given drag force can be modelled with equation Fa = dva, draw a free body...

Classification of ODEs Determine the order and linearity/nonlinearity of the following scalar ODEs (a) (10 points) y"(t) sin(t) y(t) +t2 (b) (10 points) y'(t)-sin(y(t))- t Note: If the equation is linear, vou need to prove it by the linearity property. If the equation is nonlinear, only determine the term in the equation that makes it nonlinear S. S.
Problem 3: Reduce the following system of ODEs to a system of first order ODEs and write it in the matrix form: yı + 7yi – 2y2 = 0 92 + 5y2 - 3y = 0 .
List four ways to solve a first order nonlinear differential equation in the order you would try them. What test would you apply to the ODE to determine if the method you were considering would work?

(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...
