Suppose that the position of one particle at time t is given by and the position of a second particle is given by (a) Graph the paths of both particles. How many points of intersection are there? (b)...
See AnswerQ: Investigate the family of curves defined by the parametric equations x =
Investigate the family of curves defined by the parametric equations x = t2, y = t3 - ct. How does the shape change as c increases? Illustrate by graphing several members of the family.
See AnswerQ: The swallowtail catastrophe curves are defined by the parametric equations x =
The swallowtail catastrophe curves are defined by the parametric equations x = 2ct - 4t3, y = 2ct2 + 3t4. Graph several of these curves. What features do the curves have in common? How do they change...
See AnswerQ: Graph several members of the family of curves with parametric equations x
Graph several members of the family of curves with parametric equations x = t + a cos t, y = t + a sin t, where a > 0. How does the shape change as a increases? For what values of a does the curve hav...
See AnswerQ: Graph several members of the family of curves x = sin t
Graph several members of the family of curves x = sin t + sin nt, y = cos t + cos nt, where n is a positive integer. What features do the curves have in common? What happens as n increases?
See AnswerQ: The curves with equations x = asin nt, y = bcos
The curves with equations x = asin nt, y = bcos t are called Lissajous figures. Investigate how these curves vary when a, b, and n vary. (Take n to be a positive integer.)
See AnswerQ: Investigate the family of curves defined by the parametric equations x =
Investigate the family of curves defined by the parametric equations x = cos t, y = sin t - sin ct, where c > 0. Start by letting c be a positive integer and see what happens to the shape as c increas...
See AnswerQ: For each predator-prey system, determine which of the variables
For each predator-prey system, determine which of the variables, x or y, represents the prey population and which represents the predator population. Is the growth of the prey restricted just by the p...
See AnswerQ: Each system of differential equations is a model for two species that
Each system of differential equations is a model for two species that either compete for the same resources or cooperate for mutual benefit (flowering plants and insect pollinators, for instance). Dec...
