Find the parametric equations of that tangent line. 47 of 746 < > Barrientos, Rene rbarrien@mdc.edu Ans 2. Describe graphically the curve r(t) = cosπti+sinntj+t2k,t≥0. Find the unit tangent and unit normal vectors at t= z 3. Find the arc length of one turn of the helix r(t) = b costi+bsint j + (1-b²)t k. (Hint: the integral is trivial. You just need to find when "one turn" takes place). Page 1 / 1 Q + Show details
