Quaternion multiplication meaning
Hamilton defined a quaternion as the quotient of two directed lines in a three-dimensional space, [3] or, equivalently, as the quotient of two vectors. [4] Multiplication of quaternions is noncommutative . where a, b, c, and d are real numbers; and 1, i, j, and k are the basis vectors or basis elements. See more In mathematics, the quaternion number system extends the complex numbers. Quaternions were first described by the Irish mathematician William Rowan Hamilton in 1843 and applied to mechanics in See more Conjugation of quaternions is analogous to conjugation of complex numbers and to transposition (also known as reversal) of elements of Clifford algebras. To define it, let $${\displaystyle q=a+b\,\mathbf {i} +c\,\mathbf {j} +d\,\mathbf {k} }$$ be a quaternion. The See more Just as complex numbers can be represented as matrices, so can quaternions. There are at least two ways of representing quaternions as matrices in such a way that … See more Quaternions were introduced by Hamilton in 1843. Important precursors to this work included Euler's four-square identity (1748) and Olinde Rodrigues' parameterization of general rotations by four parameters See more A quaternion is an expression of the form where a, b, c, d, are real numbers, and i, j, k, are symbols that can be interpreted as unit-vectors pointing … See more The set $${\displaystyle \mathbb {H} }$$ of all quaternions is a vector space over the real numbers with dimension 4. Multiplication of … See more The vector part of a quaternion can be interpreted as a coordinate vector in $${\displaystyle \mathbb {R} ^{3};}$$ therefore, the algebraic operations of the quaternions reflect … See more WebFirst, it is the biggest “normed division algebra”. “Division algebra” means “the numbers which can define division”. It is important when solving equations like “ax=b”. This is a fundamental when we study the number. “Normed algebra” means the number which we can define absolute value. By using absolute value,
