Hi Sean @Sean,

Could you please check out the below screenshot ? I was expecting to prove that U=Ur+Us at the second of 25. However, i did not get it when i compare with the graph, is it because it is not the 25th second, but 25th step ? or i am not sure what i am missing. Graphically also not looking to overlap for the result, also mathematically. I was trying to get the same numerical result for a certain timestep to prove for myself U=Ur+Us. Or maybe it is a visual glitch,or my visual misinterpretation?

I believe it is for the timestep, i edited post believing that i found my mistake, leaving here for anyone else who will be confused about that. The problem was the timestep to get, 25th second we shall do 25/0,02 = 1250th step.

Cheers,
Burak
