Easy way to demonstrate the accuracy of Euler's Method

[Wingman]

Hi

As the title says i am trying to find a good example (easy diffrential equation) to demonstrate Euler's method to explain it easily without a lot of calculations, help is appriciated

Are you speaking of the forward Euler numerical difference scheme?

Yes, my bad. Should have explained it a bit better. The thing is, i want to find a diffrential equation with simple approximated numerical solutions using Euler's method without a calculator or such. Later a graph can be illustrated easily on a sheet/board whithout much effort on that part either.

I have found several good examples BUT it's difficult to calculate the error without using a calculator when several of my equation involved values such as (e^t)...

Sorry but my english is poor and i find it very difficult to explain such problems.
