How to show a limit exist in maple? Im trying to show $ \lim_{x \to 0}\frac{\sin(\sin(2x)^2}{x^2} = 4 $ in maple, but I am not getting it. This is what I have
It shouldn't be that hard.  Maple has a "limit" command  Try something like limit((sin(sin(2*x)))^2/x^2,x=0);

You miscounted your parentheses so I'm guessing what you meant and I don't guarantee I counted them right, but that's how you do it.
You need to modify the condition, it should be $|f - 4| &gt; \epsilon $
