Homework Statement
whats |r'(t)| if r'(t) is <1,2t,3t2>
Homework Equations
The Attempt at a Solution
im finding normal and binormal vectors and i need to divide r(t)/r'(t)
|r'(t)| = sqrt (12+(2t)2+(3t2)2)
how does that simplify down to something that can be an appropriate denominator for r(t)=<t,t2,t3>
