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
