Homework Statement
Hi, this is part of a stats problem, in the solutions they go from:
d/dc of ln(1-0.5^c)
then next line they have:
ln(0.5).[0.5^c]/(1-0.5^c)
I don't understand how they did this!
Homework Equations
The Attempt at a Solution
So, I know that the (1-0.5^c) on the bottom comes from differentiating the natural log, and so then the top line must come from differentiating the argument, 1-0.5^c. But I don't see how they did this. I've tried to use exponentials and logs to 'bring down' the power but haven't managed to do it so far.
Could someone please point me in the right direction?
Thanks :)
