Hey guys! I was wondering how we would solve a trig function without a calculator i.e. sin 76. Or something along those lines. The calculator on the DAT doesn't have the sin, cos, or tan buttons so... ? KINDA FREAKING OUT HERE.

They won't give you anything THAT ridiculous. They could ask like sin(30,45,60,90,etc.) Just know the basic trig rules and identities and for the most part you should be set.

I think you don't need to know value of sin 76 but may ask which expression is equal to cos 76, which is -cos 76
you might want to know these identities.

You'll never need to know anything that specific. All the trig questions are either for the common angles or for identities. You will never see anything that isn't 30, 45, 60, or 90 degrees from parallel in each quadrant.

I don't think you gonna see a question like that

They may ask which expression is equal to sin(76) and the answer is cos(14).
Btw cos 76 is not equal -cos 76
