Hi, I am having some problems with an exercise.
I have solved the first one, but I don't know how to go about the 2nd one .
The first one is:
Find the solution set of |x-1|+|x+1|<1
And I got this:
(I got this from drawing the graph for |x-1| and |x+1| and adding the parallel lines)
For the second exercise I have:
Find the solution set of
I am pretty sure the result cannot be the same from looking at the graph, but I have no clue how to work it out using calculus :-/.
Any help would be very much appreciated, thanks!
