What you are saying is totally true, be adviced that the function is tideous and writing the solution(s) in equation 3.0 takes quite a time. I can gladly announce that i finally managed to solve it and will state the solution later on. Thanks anyway

Can someone help me derivate this function, I'm not sure if I got the right answer http://putfile.com/pic.php?pic=7/21115075861.jpg&s=x1

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...

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

of course, how stuiped of me :blushing: Thx for the help! :biggrin:

The domain must be then; ]0, infinity[ And the range]-1, Infinity[ or am i wrong?

so the inverse must be ln(e^x-1)?

Hi Guys, i am new to this forums and my english is poor, but i will do my best. I got stuck with this problem, i think it's quite easy, but i get the wrong answer :frown: F(x) = ln(1+e^x) 1. Show that it has an inverse 2. What is the Range And the Domain of the inverse. I really...
