Calculus

____________h__ 1. Turn in: Find the unit tangent vector T. and the principal unit normal vector N for ;(t) = (e' cost)i + (e' sin t) j + (e' )k when t = 0. The Algebra can get messy and tedious. So get started early. Make good use of trig identities. You may also want to use Geogebra to visually confirm your ndings. If you are using Geogebra, explore the vector command Vector ( ( x1, yr, 3!) , (x2. yz, 2:2) )
