In each of Questions 53–56 a pair of equations that represent a curve
parametrically is given. Choose the alternative that is the derivative .


x   =   t   −   sin t   and y   =   1   −   cos t

x   =   cos^3 θ and y   =   sin^3 θ
tan^3 θ
−cot θ
cot θ
−tan θ
−tan^2 θ

x   =   1   −   e−t and y   =   t + e−t

e−t −   1
e t + 1
e t − e−^2 t
e t − 1
and y = 1 − ln(l − t) (t < 1)

t   −   1

1    +  ln  x
