(a) The graph of r = f(θ) is symmetric with respect to the polar axis if substitution of__________for θ leads to an equivalent equation.
(b) The graph of r = f(θ) is symmetric with respect to the vertical line
(c) Alternatively, the graph of r = f(θ) is symmetric with respect to the vertical line
(d) The graph of r = f(θ) is symmetric with respect to the pole if substitution of_________for r leads to an equivalent equation.
(e) Alternatively, the graph of r = f(θ) is symmetric with respect to the pole if substitution of________for θ leads to an equivalent equation.
(f) In general, the completed statements in parts (a)–(e) mean that the graphs of polar equations of the form r = a ± b cos θ (where a may be 0) are symmetric with respect to_______.
(g) In general, the completed statements in parts (a)–(e) mean that the graphs of polar equations of the form r = a ± b sin θ (where a may be 0) are symmetric with respect to_______.
