SOLVED:Let α: I →C be a unit speed local parametrization of the oriented plane curve C. Suppose θ: I →ℝ is smooth and is such that α(t)=(α(t), cosθ(t), sinθ(t)) for all t ∈I (see Figure 10.4). (We shall, in the next chapter, be able to prove that such a function θexists; see Exercise 11.15.) Show that d θ/ d t=κ∘α

↑Let α: I →ℝ^2 be a regular plane curve and R a straight line in ℝ^2. If one can find a number t0 ∈I such that the distance from α(t) to R is greater than or equal to the distance from α(t0) to R, for all t ∈I, and such that α(t0) ∉R, then show that the tangent line of αat t0 is parallel to R. | Numerade

Eliminate the parameter t. Then use the rectangular equation to sketch the plane curve represented by the given parametric equations. Use arrows to show the orientation of the curve corresponding to increasing values of t. (If an interval for t is not specified, assume that -∞< t <∞.) x=t, y=-2 t | Numerade
