Hello,(adsbygoogle = window.adsbygoogle || []).push({});

I'm having some problems. So for geometry class today, the teacher taught us this COS, SIN, TAN stuff. I got the concept how to get the fractions from the triangle and everything. Problem is how to plug it in the calculator. I have a basic TI-30XA, and I'm trying to plug in fractions for the SIN, COS, and TAN, but I have no clue how to plug it in easily. For example the fraction : 16 over 34. How do I get the SIN of it?

Its really urgent someone replies back. I have been trying all night, and I have a chemistry test tomorrow, so I can't spend all my time working on geometry just to plug in something in the calculator.

Thanks,
