so, determine if it guarantees that a solutio exists and is
unique.

Question 2: A More detailed version of the Theorem 1 at page 24 of the textbook, called Picard's Theorem, says that If the function f(x, y) is continuous in a rectangle near the point (a, b), then at least one solution of the differential equation y' = f(x,y) exists on some open interval I containing the point If, in addition, the partial derivative is also continuous in that rectangle near (a, b), then this solution is unique on some (perhaps...

3. (Existence/uniqueness theorem, Strogatz 6.2): Consider the system (a) Show by substitution that (t) sin, () cost is an exact solution. (b) Now consider another solution, with initial condition a(0)-1/2, y(0) 0. Without doing any work, explain why this solution must satisfy y2 < 1 for all t < oo. For the systems in problems 4-7, find the fixed points, linearize about them, classify their stability, draw their local trajectories, and try to fill in the full phase portrait.

If f(x, y) is continuous in an open rectangle R = (a, b) x (c, d) in the xy-plane that contains the point (xo, Yo), then there exists a solution y(x) to the initial-value problem dy = f(x, y), y(xo) = yo, dx that is defined in an open interval I = (a, b) containing xo. In addition, if the partial derivative Ofjay is continuous in R, then the solution y(x) of the given equation is unique. For the initial-value...

In the following problems determine whether existence of at least one solution of the given initial value problem is thereby guaranteed and if so, whether the uniqueness of that solution is guaranteed. For each initial value problem determine all solutions and the intervals where they hold, if the case. (a) dy/dx = y^(1/3); y(1) = 1. (b) dy/dx = y^(1/3); y(1) = 0. (c) dy/dx =sqrt(x - y); y(2) = 1. Can you explain how can we approach these kind...
