comment $\lim_{x \to 0} [\frac {1+2cx}{1-2cx}]^{\frac {1}{x}}=?$
@PeterTamaroff : just tried something similar to that, but I think I am abusing the notation somehow, see my other dubious answer! :)

@JavaMan : I keep thinking c should be arbitrary, the fact that there is a specific value makes all this true albeit but unsettling, Thanks to Pete I think I am almost getting it.

@PeterTamaroff :aah, but then that is a stupid way of asking the question, the question should state that for a specific c, ok in this case one has to find the specific c.

@PeterTamaroff : those example are for specific k, in other words the real limit is : $\lim x_{\rightarrow 1} kx = k$, which still is confusing me. I'll ask it as a question, thank you.

does the question say for a specific c? or c can be any real number?

@PeterTamaroff : but that doesn't make sense, k is meant to be any arbitrary constant, not a specific number. Any examples of such behaviour?
