Q: Suppose that the position of one particle at time is given by
Suppose that the position of one particle at time is given by x1 = 3 sin t y1 = 2 cos t 0 (a). Graph the paths of both particles. How many points of intersection are there? (b). Are any of these poi...

If a projectile is fired with an initial velocity of meters per second at an angle a above the horizontal and air resistance is assumed to be negligible, then its position after seconds is given by th...
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 c as increases? Illustrate by graphing several members of the family.
See AnswerQ: Graph the given functions on a common screen. How are these
Graph the given functions on a common screen. How are these graphs related?
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 = -ct2 + 3t4. Graph several of these curves. What features do the curves have in common? How do they change...
See AnswerQ: The curves with equations x = a sin nt, y =
The curves with equations x = a sin nt, y = b cos t is 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 be a positive integer and see what happens to the shape as c increases...
