Homework Statement
f(x) = x ln(x)
The attempt at a solution
f'(x) = product rule, resulting in 1 + ln (x)
So by way of solving the problem, set 1 + ln (x) = 0
Now idealistically, find something in x that, when added to 1, equals zero.
Now here's a problem I have. How do I know when to keep searching for something in ln (x) and when to subtract one on both sides to make ln (x) = 1 ? And even when I get to that point, how to I move forward?
