3D Rotations | Chapter 27 Classical Mechanics 2

In this video, we'll explore the math behind representing objects in 3D. Rotation matrices are often the first (and only!) concept we're taught about 3D rotations. There are many simpler and more intuitive descriptions of the 3D rotational state of a rigid body. Euler angles (often used in gaming and rotation) are very simple, but not without their fair share of problems. These are solved by using quaternions, which are a bit harder to wrap your mind around at first, but make many computations much simpler.
