Convert
2x^(2)+5x^(3)=1+xy
into polar coordinates. Plot
r=-8cos(\theta )
for
0<=\theta <=2\pi
. Plot at least 4 points on the graph. Hint: You will need to plot several points using values of
\theta
for which you know the value of
-8cos(\theta )
. Convert
r=-8cos(\theta )
into Cartesian/rectangular coordinates. Hint: multiply both sides by
r
and compare to the graph you drew in the previous part.
