A particles position as a function of time is given by u = cos 2t i+sin 2t j ( The u, i and j should have tilde's underneath as they are vectors)
(a) find the equation of the path

x = cos(2t)
y = sin(2t)
z = 0

thats not the answer i sorta know how to do it but the 2t throws me off abit

- amistre64

thats the equation of a line in R^3 :) well, except for an initial point

the position path just produces a unit circle

- anonymous

yes i understand that but normally you would eliminiate the sin and cos by squaring x and y then adding them

- anonymous

im not sure what happens to the 2t

- amistre64

2t just modifies the speed of rotation; nothing more

- amistre64

its going twice as fast around the unit circle

- anonymous

i see so the working is like this;
x = cos 2t
y=sin2t
x^2=cos^2t
y^2=sin^2t
x^2+y^2=1
i ignore the 2t correct

- amistre64

or simply redefine it; 2t = u

- amistre64

it has no importance on position; other than it a given t it is at this location; but the path remains unchaged by it

tell me; does a person walking along the sidewalk get to the same place as the person jogging on the sidewalk?

- anonymous

yes thats correct. thanks so much you actually made me understand the question.
