9-70.

Convert the following pairs of parametric equations into rectangular form (in terms of $x$ and $y$ ).

$x =\operatorname{cos} t$ and $y = \operatorname{sin} t$

$x =\operatorname{cos}(2t)$ and $y=\operatorname{sin}(2t)$

$x = t^4 − 3t^2$ and $y = t^2$

Hint:

$\operatorname{sin}^2(x) + \operatorname{cos}^2(x) = 1$
