Use a graphing utility to determine the first three points with 020 at which the spiral r = 60 has a horizontal tangent line. Find the first three points with 020 at which the spiral r = 60 has a vertical tangent line. The first point (r,0), with 0≥0, at which the spiral has a horizontal tangent line is (0,0). (Type an ordered pair. Round to one decimal place as needed.) The second point (r,0), with 0≥0, at which the spiral has a horizontal tangent line is.
