It better be an equation!  It's just an expression again, isn't it?

Do you know of l'Hospital rule?

anonymous · Answer

yes, so I would take the derivative of the top by itself and the bottom and just plug one back in? Also, is that the only way to do it? Because I learned that in high school and am now a freshman in college and they haven't covered it yet so im not sure that they want us to use that method.

zzr0ck3r · Answer

yes this will give the answer. I am sure there are other ways of doing it, but nothing easy is jumping to my mind. What are you studying right now in class?

anonymous · Answer

It's calc 1 and we just started so we are just doing vectors and limits so far. I took the course in high school but they told me to take it again just to be safe.
