You are given two goniometric functions:

  • Male: $g(\rho, \Theta) = \rho \, \cos\Theta \sin\Theta$
  • Female: $f(\rho, \Theta) = \rho \, \cos^2\Theta$

Why are these two functions labeled "male" and "female"?

Maybe

cos = X-chromosome and
sin = Y-chromosome
Male = XY = cos * sin
Female = XX = cos * cos

  • $\begingroup$ Also, you can mention the relation between the X coordinate and cos and the Y coordinate and sin. $\endgroup$

  • $\begingroup$ @dmg : It is X & Y 'chromosomes', you must have misread as 'coordinates' :) $\endgroup$

    $\begingroup$ On the contrary, in the unit circle the cosine of the angle is equal to the displacement of X, the sine of the angle is the displacement of Y. That is why cos is X and sin is Y and not the other way around. $\endgroup$
