Homework Statement
r(t)=ti+2tj+(t^2-3)k or r(t)=(t, 2t, t^2-3)
0≤t≤2
Homework Equations
arc length formula ∫[the scalar of dr/dt]
I know I can calculate the arc length through the equation above, but the questions asks for
me to utilize this formula.
∫√(t^2+a^2) dt = .5t√(t^2+a^2) + .5a^2 times ln(t+√(t^2+a^2))
The Attempt at a Solution
I couldn't get far on this, but i think it has to do something with another alternative to get the arc length.
If it is difficult reading the problem, i also have a picture of it.
