Kvaternäärisiä
Kvaternäärisiä, or quaternions in English, are a number system that extends complex numbers. They were first described by Irish mathematician William Rowan Hamilton in 1843. Quaternions are often represented in the form a + bi + cj + dk, where a, b, c, and d are real numbers, and i, j, and k are the fundamental quaternion units. These units have the property that i^2 = j^2 = k^2 = ijk = -1.
The multiplication of quaternions is not commutative, meaning that the order of multiplication matters (e.g., ij
Quaternions have found significant applications in various fields, particularly in computer graphics and robotics. They are
