Solve the Initial Value problem

In summary, an Initial Value Problem (IVP) is a type of mathematical problem that involves finding a solution to a differential equation with a given set of initial conditions. To solve an IVP, one must first identify the type of differential equation and its order, and then use various techniques such as separation of variables, integration, or substitution to find a general solution. The steps for solving an IVP include identifying the type of differential equation, finding a general solution, using the given initial conditions to find the specific solution, and verifying the solution. Some common techniques used to solve IVPs include separation of variables, integration, substitution, and using integrating factors. IVPs are important in science because they allow us to model and predict real

dy/dt=t^(2)y^(3) , y(0)=-1

I need help solving this

I put the integral (dy/y^3)= integral (t^2)dt
but idk what to do after that or if that's even right

Hi Imanri,

You dropped an integral sign...

[tex]\int{\frac{dy}{y^3}}=\int{t^2dt}[/tex]

Do the integration on both sides.

Thank you, but after I find that what do I do with y(0)=1

You have an undetermined constant after integration. Substitute t=0 and y=-1 in your integral and solve for c.

y=-1/(t^(3)+C)
 

1. What is an Initial Value Problem?

An Initial Value Problem (IVP) is a type of mathematical problem that involves finding a solution to a differential equation with a given set of initial conditions. The initial conditions typically include a specific starting point and the rate of change at that point.

2. How do you solve an Initial Value Problem?

To solve an Initial Value Problem, you must first identify the type of differential equation and its order. Then, you can use various techniques such as separation of variables, integration, or substitution to find a general solution. Finally, you can use the given initial conditions to find the specific solution.

3. What are the steps for solving an Initial Value Problem?

The steps for solving an Initial Value Problem are as follows:

  1. Identify the type of differential equation and its order.
  2. Find a general solution using appropriate techniques.
  3. Use the given initial conditions to find the specific solution.
  4. Verify the solution by plugging it back into the original equation.

4. What are some common techniques used to solve Initial Value Problems?
