Utilizing conic section techniques to determine the point of intersection.
Plotting the graph and locating the peak value of the r function.
Given that for some constant 'm', , like other numbers may become negative or zero depending upon conditions set forth within their respective domains; therefore let's consider 'm' always being more significant than zero even though others can vary accordingly – if 'm' changes so does everything else related! ...
Number of distinctive locations peak curve occurs multiplied by a factor of four
As many local maxima as there are integer multiples between the interval [0, m] inclusive
Sum total angles divisible by the number of petals minus one
Twice the number of points where the derivative function equals zero given the interval [0, m]

How does doubling in the polar equation affect its graph's appearance compared to its original plot?
