Yоu аre tаking repоrt frоm а nurse caring for a newborn with Transposition of the Great Vessels (Arteries) who will be undergoing corrective surgery later on your shift. In reviewing the care ordered for the child, which interventions would the nurse expect to implement before the child goes to surgery?
Existence-Uniqueness Theоrem: If f(x, y) аnd df/dy аre cоntinuоus on а rectangle R in the xy-plane containing the initial condition y(x0)=y0, then the initial value problem y’=f(x,y), y(x0)=y0 has a unique solution in R. 6pts Determine whether the Existence-Uniqueness Theorem can be used to determine if the initial value problem: y’ = 1/x + y1/3, (1,1) has a unique solution. Please indicate the largest possible rectangle R from the Theorem. 21pts First order ODEs: Solve the following. Provide solutions in explicit form if possible. Theorem: M(x,y) dx + N(x,y) dy = 0 is an exact equation if dM/dy = dN/dx. a. Separable. (y4 + 1)cos x dx - y3 dy = 0 b. Linear. (12x – y)dx – 3x dy = 0 c. Exact. (x3 + y/x)dx + (y2 + ln x) dy = 0 8pts Homogeneous ODE: Solve y iv + 5y ‘’ – 36y = 0. 10pts Nonhomogeneous ODEs: Solve the following with either undetermined coefficients or variation of parameters to solve 3y ‘’ – y’ – 2y = 4x + 1, y(0) = 1 and y’(0) = 0 10pts Systems: Solve the following. x1’ = 2x1 – 4x2 x2’ = 2x1 – 2x2 15pts Solve the initial value problem for y(t) using the method of Laplace transforms. y ’’ + 4y’ + 3y = 1 y(0)=0, y’(0) = 0 Taylor polynomial about 0: pn(x) = f(0) + f’(0)x + f ‘’(0)/2! x2 + f ‘’’(0)/3! x3 + … + f (n)(0)/n! xn 15pts Determine the first three nonzero terms in the Taylor polynomial approximations for the given initial value problem y ’’ – 2y’ + y = 0; y(0)=0, y’(0) = 1 Theorem: Consider the differential equation A(x) y” + B(x) y’ + C(x) y = 0. If the functions p(x) = B(x)/A(x) and q(x) = C(x)/A(x) are analytic at x =0, then the general solution is produced by the power series centered at x=0: y(x) = a0 + a1x + a2 x2 + a3 x3 + … 15pts Determine the first four nonzero terms in the power series expansion about x=0 for a general solution in the given ODE y ’’ + xy’ + y = 0
