Solve Second Order ODE: Find a Values for Zero Tendency

In summary, the conversation discusses finding values of a for which all solutions of the given second-order differential equation tend to zero as x approaches 0+ and as x approaches +∞. The suggestion is to use the formula for finding the characteristic equation of a second-order differential equation and then examine all cases for b-(a^2/4) to determine the possible solutions.

Homework Statement



Find all values of a for which all solutions of

y''(x) + (a/x)y'(x) + (5/2)y(x) = 0

tend to zero as x tends 0+ and all values for which all solutions tend to zero as x tends to +

Homework Equations


The Attempt at a Solution



I am not even sure where to being with this problem. My guess is to examine all cases for b-(a2/4). Just not really sure on this at all.

You should know the http://math.colgate.edu/~wweckesser/math311/handouts/second_order.pdf" to a second-order differential equation to solve this.

Then look at the possible solutions based on what you have for a and x.

FAQ: Solve Second Order ODE: Find a Values for Zero Tendency

What is a second order ODE?

A second order ordinary differential equation (ODE) is a mathematical equation that involves a function and its first and second derivatives. It represents the relationship between a function and its rate of change.

How do you solve a second order ODE?

To solve a second order ODE, you need to find a particular solution that satisfies the given equation. This can be done by using various techniques such as the method of undetermined coefficients, variation of parameters, or the Laplace transform.

What does it mean to find a value for zero tendency?

Finding a value for zero tendency means determining the value of the function or its derivatives at a certain point where the function's rate of change is zero. In other words, it is finding the point where the function's growth or decay is balanced.

Why is it important to solve second order ODEs?

Solving second order ODEs is crucial in many scientific fields, including physics, engineering, and economics. It allows us to model and analyze real-world phenomena, make predictions, and understand the behavior of systems over time.

What are some applications of solving second order ODEs?

Second order ODEs have numerous applications, such as in the study of motion, electrical circuits, population growth, and chemical reactions. They are also used in many engineering and scientific problems, including control systems, heat transfer, and fluid mechanics.
