Basic trigonometry equation so I have this equation

[quaint slate]

$-10.0317 = 10.0458 * \sin(7.1726 * 10^{-4} * t)$

I solved the equation like:
$t = \frac{arcsin(\frac{-10.0317}{10.0458})}{7.1726 * 10^{-4}} = -2116.119185$
and
$t = \frac{\pi - arcsin(\frac{-10.0317}{10.0458})}{7.1726 * 10^{-4}} = 6496.110616$

What am I doing wrong?

Someone else did

$t = \frac{\pi - arcsin(\frac{-10.0317}{-10.0458})}{7.1726 * 10^{-4}} = 2263.872245$
