i have mathematica 5.0 but i dont understand a thing.

how can i make equation.

(sina * sinb - cosa * cosb) : ctga

where i can enter variables a and b as i want and then press a button which i still didnt find so i get a result. i need this for my exams. i would bring my laptop and use mathematica for much complex formulas where using calculator could lead to mistake and time consumption.

i just dont understand this program...
