Where in the problem does it state such? Sorry, I just thought 0<θ<2π means any angle from 0 to 2π which means my answer 2π/3 was acceptable. Mar 31 asked Please explain the answer to this polar-cartesian problem Mar 31 asked What is the graph of $r^{2} = 16\cos\left(2\theta\right)$ ?. Mar 31 asked What is the graph of $\theta = \frac{\pi} {3}$? Mar 26 asked Is the graph of $r^2 = 4$ a circle with radius $2$? Mar 26 accepted What is the cartesian equation of $r = 1 + r \sin(\theta)?$ Mar 26 asked What is the cartesian equation of $r = 1 + r \sin(\theta)?$ Mar 20 comment What is the graph of $r \cos \theta = 3$? Holy crap it was that simple. Thanks! Mar 20 comment What is the graph of $r \cos \theta = 3$? If I will divide it by 3, I'll only get r but not the theta part, leaving me no clue about its graph. Mar 20 comment What is the graph of $r \cos \theta = 3$? I know the formulas, but what do I plug in the theta part? Mar 20 accepted What is the graph of the polar equation $r = e$? Mar 20 asked What is the graph of $r \cos \theta = 3$? Mar 20 asked What is the graph of the polar equation $r = e$? Mar 19 accepted What is the graph of the polar equation theta = pi? Mar 19 comment What is the graph of the polar equation theta = pi? Cool cool cool. Thanks!
