While trying to quickly copy a problem from the board I think I made a mistake. What I wrote down:
lim http://www.mathhelpforum.com/math-he...974b7693-1.gif
x->1+
doesn't coincide with the first step of the solution:

What could the original problem have been to have this as a first step in the solution?
