41 - 50. The line is given by the equation r = r (φ) in the polar coordinate system. It is required: 1) to construct a line on points, starting from φ = 0 to φ = 2π and giving φ values through the interval π / 8; 2) find the equation of this line in a rectangular Cartesian coordinate system, whose origin coincides with the pole, and the positive semiaxis of abscissas with the polar axis; 3) determine the line by the equation obtained.

46. r = 5 / (3 - 4cosφ)
