Heba Dousa it really depends on your school district, but I'm pretty sure that if you are In Geometry 1 and above, they are required to give you a calculator, (that is the class that trig is first introduced) however if they don't I'm sure they will tell you a way to do so, so you have no need for worry my friend 🙂
