I have a function that states:(adsbygoogle = window.adsbygoogle || []).push({});

[tex]e^{\frac{-t}{k}}\sin2t[/tex].

With the restriction k>1. There shouldn't be a dot next to the t.

I am meant to figure out why k is always bigger than one but so far, I am hatting a brick wall. Obviously, zero doesn't work because it yields a math error but the other decimals such as 0.9 or 0.8 can be graphed perfectly.

Could someone please give me anyhints? I am thinking it might have something to do with time now but I am still blank.
