Solve Initial Value Problem Using Exponential Functions | Step-by-Step Guide"

If m=0, then the DE becomes y'' + 9y' = 0. In summary, the conversation is about finding the values of m that will make the given differential equation equal to zero. This is done by using the quadratic formula to factor the equation into (m + 9)(m + 1) = 0, and then finding the roots of m that will make this equation true, which are m = -9, -1, and 0.

is there a question?

also I would outline your initial assumption to help, and as a start look at putting a constant through your DE

yes the question is here:

If [itex]m(m+9)(m+1)=0[/itex], [itex]=m-1[/itex] and [itex]m=-9[/itex] aren't the only possible values of [itex]m[/itex] are they?:wink:
 
  • #5
yes, but web assign for some reason won't accept that answer
 
  • #6
You have a cubic equation, so there should be 3 roots...you've only listed two of them...
 
  • #7
what's the other one? m = 0?
 
  • #8
Yep.
 

What is an initial value problem?

An initial value problem is a mathematical problem that involves finding the unknown function using a given initial condition. In other words, it is a differential equation that must be solved for the unknown function with the help of the initial condition.

What are exponential functions?

Exponential functions are functions in which the independent variable appears as an exponent. In simple terms, these functions have a constant base and a variable exponent. They are commonly used to model situations involving growth or decay.

How do you solve an initial value problem using exponential functions?

To solve an initial value problem using exponential functions, you need to first express the given differential equation in terms of the unknown function and its derivative. Then, you can use the initial condition to solve for the constant of integration and find the particular solution.

What are the steps involved in solving an initial value problem using exponential functions?

The steps involved in solving an initial value problem using exponential functions are:

  1. Express the given differential equation in terms of the unknown function and its derivative.
  2. Apply the initial condition to find the constant of integration.
  3. Use the constant of integration to find the particular solution.
  4. Check if the particular solution satisfies the original differential equation.

What are some common applications of solving initial value problems using exponential functions?

Solving initial value problems using exponential functions is commonly used in various fields of science and engineering, such as physics, chemistry, biology, and economics. It can be used to model and predict growth or decay in populations, chemical reactions, radioactive decay, and many other natural phenomena.
