a) Check the 1st differences of the consecutive y-values. Since they are nearly constant, we can use a linear model.

b)At the WolframAlpha web site you can enter: fit linear

I want to find this limit for complex variable z

$\underset{z\to -1}{lim}(z+1)\mathrm{sin}\left(\frac{1}{z+1}\right)$

In the real case I know sin(z) is bounded by -1,1, and the limit is 0. But in the complex case$\mathrm{sin}\left(z\right)$ is not bounded. How can I find the limit or prove that it doesn't exist?
