- Consider the parametric curve Determine which of the following graphs is the correct image of this curve: The correct graph is (Select One) v(1) = r(t) = ( −t³, −t² ) . A B D Also, compute the velocity and acceleration vectors at t = 1, and use this information to determine the direction of motion for the curve. a(1) = The direction of motion is (Select One) Usage: To enter a vector, for example (x, y, z), type "" сarrow_forwardA little help regarding curvature?

- Parametrize the sine curve y = sinx using the parametrization r(t)=(t,sint), t ∈ R. (a) show that this curve is smooth. (b) Compute the curvature, and find all points where the curvature is zero. What geometric property do all those points share? (c) Without doing any computations, explain why the torsion of this curve must be identically zero. (d) Rotating the plane 30◦ is an isometry, which transforms the original sine curve into the curve parametrized by r(t) = √3t −sint 2 , t + √3 sint 2 , t ∈ R. Compute the speed, curvature, and torsion of this curve, and compare them to those of the original curve. (e) By graphing the curve, decide if it is the graph of some function y = f(x). (f) In single-variable calculus, you studied the qualitative properties of the graphs of functions y = f(x). In particular, you characterized the maxima, minima, and inflection points in terms of the vanishing of certain derivatives of the function f(x).
