(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The given curve is r(t) = <t^{2}, 2t, -3>

Write an equation for the length of the curve from <0,0,-3> to <1, 2, -3>

2. The attempt at a solution

I take the derivative of r(t) for r'(t), then plug it into the length formula.

L = ∫ of √( (2t)^{2}+ 2^{2})

For the Integral, I put from0 to 1, because in the original equation, the x component t^{2}= 1 when t is 1, and the y component 2t = 2 when t is 1.

Am I doing something wrong? o_o
