No they most certainly are not allowed. You should memorize easy roots like Sqrt[2] and Sqrt[3] and their inverses just for time's sake. That and remember how to do long division (yuck!)

Nope, no calculators. Another thing you might want to memorize is the sins of the five most commonly used angles.

I know it's stupid, but since I've got a bad memory, I found this little trick helpful in memorizing them:

sin(0)=sqrt(0)/2=0

sin(30)=sqrt(1)/2=1/2

sin(45)=sqrt(2)/2=sqrt(2)/2

sin(60)=sqrt(3)/2=sqrt(3)/2

sin(90)=sqrt(4)/2=1

Calculators are not allowed for the exam.

I thought I am having memory depletion, but alas....
