Can you explain how I find the values so I can plot a graph of
T=(25 ln24/ln) -(25/ln2) ln M
well, first get rid of the typos.
What is (25 ln24/ln)?
If you mean, as I suspect you do,
(25 ln24/ln2) then collapse all those constants.
(25 ln24/ln2) = 114.62
25/ln2 = 36.07
So, what you have is just
T = 114.62 - 36.07 lnM
You know what the graph of lnM looks like. So,
flip it upside down to get -lnM
multiply by 36.07
shift it up by 114.62
Or, just grab your favorite calculator and plot a few points.
