- Hi Guys, I am trying to understand the derivation of the diffusion/heatwave equation, but I am stuck on how the person managed to get ##k^2##. I have attached the slide to this thread.
When the delta t and x approached zero, assumably it results in the whole fraction to be zero. The slide shows it will be ##k^2##. Can someone explain this to me, please?
P.S. I have tried to search this up, I could not find anything related to the confusion.
