WebDec 29, 2024 · The dot product provides a quick test for orthogonality: vectors →u and →v are perpendicular if, and only if, →u ⋅ →v = 0. Given two non-parallel, nonzero vectors →u and →v in space, it is very useful to find a vector →w that is perpendicular to both →u and →v. There is a operation, called the cross product, that creates such a vector. WebJan 8, 2024 · We say that two vectors a and b are orthogonal if they are perpendicular (their dot product is 0), parallel if they point in exactly the same or opposite directions, and never cross each other, otherwise, they …

WebIn linear algebra, an orthogonal matrix, or orthonormal matrix, is a real square matrix whose columns and rows are orthonormal vectors . One way to express this is where QT is the transpose of Q and I is the identity matrix . This leads to the equivalent characterization: a matrix Q is orthogonal if its transpose is equal to its inverse :
