Math 244 Fake Final Exam 2e syatem 13. 116 points Consider the non-linear system dt a) Use r -x2 + y2 to write dr as a function of r. b) This system has a limit cycle. Identify it, and determine whether it is stable or unstable. dr (t may help to draw the phese ine for the DE di )) e) The systemhas only one critical point, at the origin. (You do not need to prove this.) What, specifically,...
A square wave of amplitude A and period T can be defined as -A, 5<t<0, with f(t) = f(t + T), since the function is periodic. Compute the Fourier series for the function in the form f(t) = aneinwot, n=- where wo = 21/T and the coefficients an are the complex Fourier coefficients. Show all your work. Make a simple sketch of the signal and its series. The FIR filter is defined by the filter coefficients bk = [3,-1,2,1] Write...
Solve the initial value problem for r as a vector function of t. dr Differential equation: = -32k . = 21 + 2] Initial conditions: r(0) = 60k and r(t) = (i+1+OK
Problem 5. Letf be the function defined in the previous problem, So t) dr 0 Show that the inverse of this function is a solution of the differential equation y = 1. That is, let g(t) (). Show that (t)= 1 - g(t). This is a kind of "Pythagorean identity" for this function g and its derivative. It says that the parametric curve (t) = (g(t),gf(t)) has its image in the solution set of the equation y21- . Use Wolfram...

1. The Duffing equation is a non-linear second-order differential equation used to model certain damped and driven oscillators. The equation is given by -ax+3x3 = cos(wt) at medt dr. where function r = r(t) is the displacement at timet, is the velocity, and is the acceleration. The parameter 8 controls the amount of damping, a controls the linear stiffness, B controls the amount of non-linearity in the restoring force, and 7 and w are the amplitude and angular frequency of...
