Given $$f(x) = \frac{1 - \mathrm{cn}(x,k)}{{\sqrt3}(1+\mathrm{cn}(x,k)) - 1 + \mathrm{cn}(x,k)}$$ what would be $$\lim_{x\to 0} f(x)$$ and $$\lim_{x\to\infty} f(x)$$ when $$k=\frac{\sqrt{2-\sqrt{3}}}{2}?$$

    What's $cn(x,k)$? Also, you seem to have unbalanced parentheses in the denominator of $f(x)$.2011-07-24

    What's $\mathrm{cn}(x,k)$? The elliptic function usuallty denoted $\mathrm{cn}(x,k)$.2011-07-24

    Thanks, I guess the `elliptic-functions` tag should've clued me in.2011-07-24
