Hi all,
I'm a math major at Berkeley with a 3.3 GPA average. I've taken calculus, linear and abstract algebra, probability and real analysis. The other day I was applying for a job as a pre-Calculus teaching assistant and my employer gave me this problem with a 2 minute time limit.
Simplify this expression:
[tex]\frac{\frac{1}{x}+1}{\frac{1}{x}-1}<2[/tex]
I couldn't get it.
