How to Use the Differential Equations Calculator (Step-by-Step)

Using the tool is simple. Here’s a walkthrough:

Step 1: Choose the type of equation

  • Select from the dropdown:
    • First Order Linear (y’ + P(x)y = Q(x))
    • Separable (dy/dx = f(x)g(y))

Step 2: Enter your equation

  • Type your differential equation in the input box.
  • Example for linear: y' + 2y = x
  • Example for separable: y' = x*y

Step 3: (Optional) Enter initial condition

  • You can specify values like y(0)=1 to get a particular solution instead of the general one.

Step 4: Click Calculate

  • The tool will show a progress bar and then display:
    • The solution in LaTeX format (mathematical notation)
    • Step-by-step explanations
    • How to apply the initial condition

Step 5: Copy or Share Results

  • Use the Copy Results button to save your solution.
  • Use Share to send your solution via supported apps.

Step 6: Reset if needed

  • Click Reset to start over with a new problem.

Practical Example

Let’s solve an equation using the calculator:

Problem: Solve y' + 2y = x, with the initial condition y(0)=1.

Steps in the calculator:

  1. Select First Order Linear.
  2. Enter y' + 2y = x.
  3. Enter y(0)=1 as the initial condition.
  4. Click Calculate.

Solution Output:

  • General solution: y(x)=e−2x(∫e2x⋅x dx+C)y(x) = e^{-2x} \left( \int e^{2x} \cdot x \, dx + C \right)y(x)=e−2x(∫e2x⋅xdx+C)
  • Step-by-step explanation shows integrating factor method.
  • Applying y(0)=1 gives a specific solution with constant C determined.

This example demonstrates how quickly the tool generates not only the solution but also the reasoning behind it.
