Considering our linearisation, define X (either directly or via lambdifying a symbolic expression) to contain the numerical values of the natural logarithm of the number of masses (1,2,3, and 4).

Then, print this numpy array and copy and paste the output of this print call directly into the input cell below without any changes. 

E.g. if you have used the variable name X as suggested for the ln(n), then add the line

print(X)

to your code and then copy from the terminal or console the output that this line generates and paste this into the text cell below without making any changes.
