Construction of the limaçon r = 2 + cos(π – θ) with polar coordinates' origin at (x, y) = ( 1 / 2 , 0). In geometry, a limaçon or limacon / ˈ l ɪ m ə s ɒ n /, also known as a limaçon of Pascal or Pascal's Snail, is defined as a roulette curve formed by the path of a point fixed to a circle when that circle rolls around the outside of a circle of equal radius.
The inner loop is defined when + on the polar angle interval / /, and is symmetric about the polar axis. The point furthest from the pole on the inner loop has the coordinates ( a , 0 ) {\displaystyle (a,0)} , and on the polar axis, is one-third of the distance from the pole compared to the furthest point of the outer loop.
The 777-200 aircraft were found to differ from Boeing’s current design. In particular, the wiring to the first officer’s oxygen mask light plate differed in the follow aspects: a wire clamp was missing, the wiring was not sleeved, and a large loop of unsupported wire was found.
Earth's inner core, a super-hot and super-compressed ball of iron smaller than the moon, helps generate the Earth's magnetic field and, by extension, the aurora borealis -- or Northern Lights.

Using either one of the polar representations above, the area of the interior of the loop is found to be /. Moreover, the area between the "wings" of the curve and its slanted asymptote is also 3 a 2 / 2 {\displaystyle 3a^{2}/2} .
Mitosis in eukaryotes: In mitosis, loop extrusion by condensin is critical for the segregation of sister chromatids and for providing structural rigidity after separation. Condensin I has been found to modulate the size and arrangement of nested inner loops and condensin II organizing the backbone from which loops emanate. [4]
A cardioid The caustic appearing on the surface of this cup of coffee is a cardioid.. In geometry, a cardioid (from Greek καρδιά (kardiá) 'heart') is a plane curve traced by a point on the perimeter of a circle that is rolling around a fixed circle of the same radius.
