Find the parametric equations for the tangent line to the curve with the parametric equations at the point (-1, 1, 1). Solution: Note: Sometimes, it is convenient the normalize a vector tangent to a vector valued function. This gives the unit tangent vector. Unit Tangent Vector. Given a vector function . r. on an open interval I, the unit ...
