You can make them have the same denominator and then compare
so as you can see,
<span>we are given the function r=2cos(3θ)
from the pythagorean theorem,</span>
<span><span>r2</span>=<span>x2</span>+<span>y2
from the polar definition,</span></span>
<span>x=rcos3θ</span>
<span><span>x/r = </span>cos3θ</span>
<span>y=rsin3θ</span>
<span>r=2<span>x/r</span></span>
<span><span>r2</span>=2x</span>
<span><span><span>x2</span>+<span>y2</span>−2x=0.
This equation represents a parabola</span></span>
