Understanding checked vs unchecked exceptions in Java

Why are quaternions used for rotations?

Note that all of these representations of rotations are used in practice. Euler angles use the least memory; matrices use more memory but don't suffer from Gimbal lock and have nice analytical properties; and quaternions strike a nice ...
