Solve the diffusion equation with python

Web1 day ago · A summation expression is just a for loop: in your case, for k in range (1, n + 1), (the +1 to make it inclusive) then just do what you need to do within it. Remember that 0.5% is actually 0.005, not 0.5. Also remember that 1-0.5%* (n/365) is a constant, because n is 4. Do it by hand for the first 2/3 rows post the results.
