Doing some self prep for Diff EQ starting next week.
Determine the decay rate of C14 which has a 1/2 life of 5230. Using e^kt as a function,
I solve using k5230=ln.5 which gives the obvious answer of negative what I want. How do I know to use the reciprocal (ln2) other than to "just know" I want the positive k value? What if I'm looking for something where I may want a negative but don't know it? Will there be such an instance?
-thx
