PIThe surface area of a sphere is given by the formula 4πr² 📐✨. It’s derived by relating a sphere to a cylinder: if you unwrap the curved surface, it equals four times the area of a circle with the same radius. This elegant result shows how geometry connects shapes in surprising ways.

EXCoordinate Systems | Cartesian and Polar
Explore the fundamental connection between Cartesian and polar coordinates in this short video about coordinate systems. Discover how Cartesian coordinates, defined by horizontal (x) and vertical (y) distances, seamlessly relate to polar coordinates, represented by distance (r) from the origin and angle (θ) with respect to the horizontal axis.
Polar coordinates offer a different perspective on describing points in a plane compared to Cartesian coordinates. They’re particularly useful in scenarios where circular or rotational symmetry is involved, such as in physics, engineering, and mathematics.
One significant advantage of polar coordinates is their ability to simplify equations, especially those involving circular or radial patterns. For example, equations describing curves or shapes with rotational symmetry, like circles, ellipses, spirals, and sectors of circles, are often more straightforward in polar form.

THSpherical (r, φ, θ) to Cartesian (x, y, z):
x = r * cos(θ) * sin(φ)
y = r * sin(θ) * sin(φ)
z = r * cos(φ)
Cartesian (x, y, z) to Spherical (r, φ, θ):
r = √(x² + y² + z²)
φ = arccos(z / r)
θ = arctan(y / x)
These are spherical coordinates. They were used in part of this animation to calculate the spheres. Spherical coordinates define locations in space with three values. The distance from the center, called the radius, denoted by the letter r, the angle away from the north pole, or polar or zenith angle, denoted by the letter φ (“phi”), and the angle around the pole, call the azimuthal angle, denoted by the letter θ (“theta”). These three quantities can define any location in three-dimensional space.
Alternatively, rectilinear coordinates, or Cartesian coordinates, also define any location in three-dimensional space, but instead use the three quantities of x, y, and z, the distances in the right-left, forward-backwards, and up-down directions.
The equations above shows the relationship between the two coordinate systems, that is, if you have the three values from the one system, you can use these equations to find the three values in the other system.
If we are to truly awaken genius, we must see these equations as descriptions of a self-evident mathematical truth. Not simply memorize them, but learn to see them as descriptions of something we know. Can you see it?
This animation was created with the Java programming language in the Processing IDE (interactive development environment). Below you can see a snippet of code that uses spherical coordinates to generate the frames in this animation.
float theta = map(i, 0, n, 0, TAU);
float thetaStep = TAU / n;
float x = r * sin(phi) * cos(theta);
float y = r * sin(phi) * sin(theta);
float z = r * cos(phi);
AVector v = new AVector(x, y, z);
v.rotateY(rotatePhi);
v.rotateZ(rotateTheta);

THEver wondered how we actually calculate the volume of a sphere? 🌍
It’s more than just a formula you memorize. By using spherical coordinates, we can integrate through 3D space to find Volume.
Watch how these variables build the sphere from the ground up! 📐✨

MAThis visual represents the unit circle, and how the value of the sine of theta varies as the angle theta increases. Sine of theta can be thought of as the y coordinate as we move along the unit circle. The reason for this is because the unit circle has a radius of 1 by definition, which is the hypotenuse of the right angled triangle. Now, as we move along the arc of the circle, starting from the coordinate (1,0), our x and y positions change. We can call the angle between the x axis and the hypotenuse theta, and by simple trigonometry we see that the y coordinate is always the sine of theta!
