    Re: parametric equation

    I assume that the "r" and " \theta" are polar coordinates. Then x= rcos(\theta) and y= rsin(\theta). Replace r with your given equation to get equations for x and y in the parameter \theta.

    Re: parametric equation

    I got the answer.

    f(t)= 2 (theta/360) cos(t) g(t) = 2(theta/360)sin(t)



    Thanks.
