Transform to a Cartesian Equation:

a. x = sin t
y = cos t

b. x = t^(1/3) -1
y = t^2 - t

---
This is what I have for B so far:
y = t(t-1)
t = (x+1)^3

y = (x+1)^3[(x+1)^3-1]
= (x^3 + 3x^2 + 3x + 1)[x^3+3x^2+3x]
...???

and IDK about A.

Help?

Thank you so much!

    A: x^2 + y^2 = 1
    This plots as a circle around the origin with radius = 1.
