Consider the curve described by the vector function r(t) = (50e -t cos t)i + (50e -t

Question:

Consider the curve described by the vector function

r(t) = (50e^-t cos t)i + (50e^-t sin t)j + (5 - 5e^-t)k, for t ≥ 0.

a. What is the initial point of the path corresponding to r(0)?

b. What is lim r(t)?

c. Sketch the curve.

d. Eliminate the parameter t to show that the surface on which the curve r(t) lies is z = 5 - r/10, where r² = x² + y².
