In summary, the conversation discusses a homework statement involving a differential equation with the task of showing that the solution with a given initial condition has a vertical asymptote at a certain point. The person is having trouble solving the equation for y due to the negative sign and is seeking help from others.

Homework Statement



For the d.e

y' = x^2+y^2

Show that the solution with y(0)=0 has a vertical asymptote at some point x_0,
Then I have to try and find the upper and lower bounds for x_0

I'm not able to solve this for y because when I bring the y^2 to the LHS


The Attempt at a Solution



I'm trying to learn differential equations on my own though readings and I'm having trouble getting the hang of it... for the above question I tried a few things such as

y' - y^2 = x^2

I've tried a number of methods including multiplying throughout by x and I can't
find an equation whose differential is y' - y^2 OR xy' - y^2 because of the
negative sign? SO my main prob is I can't begin to solve it for y(0)=0 because I
don't know how to find y? Any help will be much appreciated!

This looks like a Riccati differential equation.
 

What is a first order differential equation?

A first order differential equation is an equation that involves a function and its first derivative. It is typically written in the form of dy/dx = f(x,y), where y is the dependent variable and x is the independent variable. Solving a first order differential equation involves finding a function that satisfies the given equation.

What are the methods for solving a first order differential equation?

There are several methods for solving a first order differential equation, such as separation of variables, integrating factor, and substitution. Each method may be more suitable for certain types of equations, and it is important to understand the strengths and limitations of each method.

What is separation of variables method?

Separation of variables is a method for solving first order differential equations where the equation is rearranged so that all terms involving the dependent variable y are on one side and all terms involving the independent variable x are on the other side. The resulting equation can then be integrated on both sides to find the solution.

What is the role of initial conditions in solving a first order differential equation?

Initial conditions, also known as boundary conditions, are values that are given to the dependent variable y and/or its derivative dy/dx at a specific point or interval. These conditions are necessary to uniquely determine the solution to a first order differential equation, as there may be multiple functions that satisfy the equation without the initial conditions.

What are the applications of solving first order differential equations?

First order differential equations are used to model various real-world phenomena, such as population growth, radioactive decay, and chemical reactions. They are also essential in fields such as physics, engineering, and economics for predicting and understanding the behavior of systems over time.
