Ia | Modeling A Chicken Egg Math

Why an egg? At first, it sounds simple. But an egg isn’t a sphere, an ellipsoid, or an oval—it’s a unique mathematical object with one blunt end, one pointed end, and a perfect curve. And since I love calculus and real-world applications, this felt like a goldmine. My research question is: How can we model the 2D profile of a chicken egg using a combination of functions, and then use calculus to find its volume and surface area? The goal: create a mathematical model that fits an actual egg’s silhouette, then compare theoretical vs. measured volume (using water displacement). Step 2 – Gathering Data I took a standard large chicken egg, traced its outline on grid paper, and digitized key coordinates. Then came the hard part: finding an equation that fits.

(more painful, but doable):

Here’s a draft post for a Math IA (Internal Assessment) blog or forum, written from the perspective of an IB student. It focuses on modeling a chicken egg’s shape using calculus and coordinate geometry. From Breakfast to A*: Modeling a Chicken Egg for My Math IA modeling a chicken egg math ia

This equation worked beautifully for the top half. The bottom half is symmetric (y negative). Once I had ( y = f(x) ) for the upper half (from ( x = -L/2 ) to ( x = +L/2 )), I used: Why an egg

(around the x-axis):

[ y = \pm \frac{B}{2} \sqrt{\frac{L^{2} - 4x^{2}}{L^{2} + 8wx + 4w^{2}}} ] And since I love calculus and real-world applications,
