This online calculator is provided to you at zero cost and implements Euler’s method. It is developed as a first order numerical method to solve first degree differential equations with a given initial value (that is dy/dx).

You can use this calculator to solve first degree differential equations with a given initial value using Euler’s method as explained above.

To use this method, you should have a differential equation in the exact form of y’ = f(x, y). Enter the values for the right side of the equation f(x,y) in the y’ field provided to you in the calculator.

You will also need an initial value as and when the point for which you want to approximate the value.

The last parameter of this method is of a step size. It is literally a step along the tangent line in order to compute the next approximation of a function curve.

If you know the exact solution of a differential equation or can have it computed in the form y=f(x), you can enter it as well.

Here, the calculator plots the solution along with approximation on the graph. It also computes the absolute error for each step of the approximation.
