Find the points of intersection for the polar curves r = 2 sin(2θ) and r = 2 cos θ. Homework Help ✎
Set the equations equal to each other (because r = r).
Divide both sides by 2.
Apply the Double Angle Identity for sine.
Set the equation equal to 0 and factor.
Use the Zero Product Property to solve for θ.
Use your values for θ to solve for r.
Verify your answers and that you found all points of intersection by graphing.
