The function we used here is: 
Highlights:
- Double Derivation is performed on the function f(x,t).
- The PDE formed is
- Initial Conditions taken as : f(x,0) = sin(x)
- Boundary Conditions taken as: f(0,t) = 0 and f(L,t) = sin(L)*exp(-t)
The code provided here contains a comparison between the original function and the function we made using PDE to check if both the graph coincides
