Define input variable theta as discretized row vector $($i$.$e$.$ array$)$

theta $=x$

Define radius

$r=y$

Define $x$ and $y$ in terms of theta and $r$

$x=$ theta

$y=$ radius

Check that $x$ and $y$ satisfy the equation of a circle

Explain results here. Do $x$ and $y$ satisfy the equation of a circle? Why or why not?

How does the vector output at the end confirm your answer?
