- Write the definition of the derivative of a function of x as a lim
I have no idea what this is talking about.
- Consider
H(x) = \begin{cases} x(1-cos(\frac{1}{x})) & \text{x$\neq$0} \\ 0, & \text{$x=0$} \end{cases}
Using the limit definition of the derivative find H'(0). If that limit does not exist, explain why.
I feel like the limit does exist, and I'm just missing something.
A reply today would be appreciated.
