Thanks anon,
You are best to do it all at once and then you will get less rounding error. :)
sin(24.6)/cos(62.1)
$${\frac{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{sin}}{\left({\mathtt{24.6}}^\circ\right)}}{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{cos}}{\left({\mathtt{62.1}}^\circ\right)}}} = {\mathtt{0.889\: \!622\: \!288\: \!584\: \!947}}$$
