Good evening,
I was doing some calculations with R when I noticed an error in one of
the answers.
I am attaching the screenshot of the page. There you will see that the two
calculations are written in a different way but they should give the same
result, because they're equivalent.
Let me know if it is a solvable problem,

Kind regards
