Sorry for the late answer but here goes:

You simply select sin, cos or tan. Then it should say something like $${tan}\left($$

Type the amount of degrees the angle is and close the parenthesis: $$\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}{\left({\mathtt{50}}^\circ\right)}$$

So let's say I wanted to use tan to figure out a in an right-angled triangle. I have Angle A and side a

The formula is $${\frac{{\mathtt{a}}}{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}{\left({\mathtt{A}}\right)}}}$$, so I go: $${\frac{{\mathtt{5}}}{\underset{\,\,\,\,^{\textcolor[rgb]{0.66,0.66,0.66}{360^\circ}}}{{tan}}{\left({\mathtt{50}}^\circ\right)}}} = {\mathtt{4.195\: \!498\: \!155\: \!887\: \!139\: \!2}}$$

Hope this helped even though it probably didn't...
