ATTENDANCE QUESTION 1:
Let a=7th digit of your RUID
Let b=9th digit of your RUID
Find curvature of the curve
R(t)=<t^a, t^b, t^(2a)> at point <2^a, 2^b, 4^a> 
My RUID: 201000735

ANSWER TO ATTENDANCE QUESTION !:
a=7 and b=5
R(t)=<t^7, t^5, t^14> 
p=<128, 32, 16384> POINT IS SO LARGE
K=T’(t)/r’(t)
T(t)=r’(t)/magnitude[r’(t)]
Take derivative of T(t) and plug into K equation
Then plug in <128, 32, 16384> into K

ATTENDANCE QUESTION 2:
