A point starts at ( x , y ) = ( 5.5 , 0 ) and moves CCW along a circular path centered at ( x , y ) = ( 0 , 0 ) . Imagine an angle with a vertex at the center of the circular path subtending the path the point has traveled. Let θ represent the angle's measure (in radians). Write formulas expressing the x and y -coordinates of the point in terms of θ .
