Question

A snake is traveling in the sand along the path shown. If the snake's head was at the origin at t = 0 and x = 2 at t = 1, which set of parametric equations will predict the location of the snake's head at any given time t?




A. X(t)=t

Y(t)=sin(2πt)

 

B. X(t)=sin(2πt)

Y(t)=t

 C.x(t)=sin(2πt)

Y(t)=cos(t)

 

 D. X(t)=cos(2πt)

Y(t)=sin(t)
 

Answer 1

There must be some typo, none of these answers work. Plug in t=1 to all the x equations, none of them will result in x=2 at t=1.
