Parameterize the motion of an object traveling a circular path clockwise beginning at a point (4,0). The object completes one revolution in 3.14 seconds. It has to be in the form of x=sin( ) and y=cos( ).

What have you tried?

Where are you stuck? - Aug 16th 2011, 04:47 AMHallsofIvyRe: Need help understanding this please!!!!!!!!!
Your answer

**can't**be in the form x= cos( ), y= sin( ) because will never give (4, 0). Did you mean x= Acos( ), y= Asin( ) for some constant, A? - Aug 16th 2011, 05:23 AMSorobanRe: Parameterize the motion of an object traveling a circular path.
Hello, cdiesel89!

Please give us the original wording.

clockwise beginning at a point (4,0). . Where is the center?

The object completes one revolution in 3.14 seconds.

It has to be in the form: .

The given forms are for acircle (radius 1).*unit*

There are a brizillion possible circles.

One of them has it center at (3,0).

Its equation is: .

The parametric equations are: .

HallsofIvy is correct.

If the center is at the Origin and the radius is to be 4,

. . the forms must have a leading coefficient.

One set of parametric equations is: .

If the period is to be seconds, let

. . where is in seconds.
