Homework Statement
Hi, my question is
lim[itex]_{x\rightarrow0}[/itex]x2[itex]\frac{cos(cot(x))}{sinx}[/itex]
Homework Equations
The Attempt at a Solution
I thought maybe I could make [itex]\frac{cos(cot(x))}{sinx}[/itex] similar to [itex]\frac{sinx}{x}[/itex], but couldn't find a proper way for it. Dividing sinx by cosx and multiplying does not take me anywhere, neither does trying to manipulate cotx. Is there something I need to see but cannot see?
L'Hospital and derivatives are not valid solutions since we haven't learned them yet.Could you please help me find a way? Thanks for any help.
