Sinusoidal Functions: Hair



 Sofia's curl pattern follows the same structure and flow of a sinusoidal function. There is a clear pattern of symmetry when the shape of the function forms, and we can see that evidently in Sofia's hair. From the photo I took of Sofia's curl, we can see that her hair has a natural dip, followed by a hump, and followed by another dip. This formation of a dip followed by a hump, or a high point to a middle point to a low point to a middle point to another high point (HOLOH), is a direct representation of a sinusoidal function. In Sofia's case, where her hair follows that HOLOH pattern, her curl resembles a Cosine function, which would take the mathematical formula of y = cos(x).

Square root of a Function: Nails

Image
  The fingernail, specifically when grown out to a longer length, resembles the square root of a parabolic function. The nail creates a shallow curvature which curls against itself at the ends, reflecting the same shape as that of a square root of a parabola. The square root of a parabola creates this shape as it follows the transformation of y =  √f(x) or (x, √y) , and because of this specific application the nature of square rooting a function is that the transformation line will go larger (outside) of the original parameters, as fractions become larger numbers rather than smaller, creating the curl at the end of the line like the nail does.

Unit Circle in Radians: Nose

Image
Noses in general share a resemblance to a section of the unit circle in radians, but this photo of my grandpa, particularly showcases the resemblance between a human nose and a radian, as the tip of his nose creates a beautiful arc below a prominent triangular shape. Though his nose does not create a perfect radian, as the arc length of his nose does not equal the radius or arm length of the triangular portion, it is evident that this specific nose shape/ratio creates a value of around  π/6 .
