Another one that I can 't get:

$\displaystyle \displaystyle \lim_{t\to 0 } \frac {sin^2 3t}{t^2}$

Can I convert this to:

$\displaystyle 9 * \displaystyle \lim_{t\to 0 } \frac {sin^2 t}{t^2}$

If so, then the solution seems easy ($\displaystyle 9 * 1 = 9$)

But I suspect that my algebra is faulty.

Thanks.
