This is a list of unsolved problems in chemistry. Problems in chemistry are considered unsolved when an expert in the field considers it unsolved or when several experts in the field disagree about a solution to a problem.
The Kenya Certificate of Secondary Education (KCSE) is an academic certificate awarded to candidates upon completion of secondary education in Kenya. [1]The first KCSE exam was held in 1989 at the same time as the last Kenya Advanced Certificate of Education (KACE), which it replaced as the entrance requirement for Kenyan universities.
Several important classes of matrices are subsets of each other. This article lists some important classes of matrices used in mathematics, science and engineering. A matrix (plural matrices, or less commonly matrixes) is a rectangular array of numbers called entries. Matrices have a long history of both study and application, leading to ...
The Hadamard product operates on identically shaped matrices and produces a third matrix of the same dimensions. In mathematics, the Hadamard product (also known as the element-wise product, entrywise product [1]: ch. 5 or Schur product [2]) is a binary operation that takes in two matrices of the same dimensions and returns a matrix of the multiplied corresponding elements.
In the case where V is of finite dimension n it is common to choose a basis for V and identify GL(V) with GL(n, K), the group of invertible matrices on the field K. If G is a topological group and V is a topological vector space , a continuous representation of G on V is a representation ρ such that the application Φ : G × V → V defined by ...
[8] [9] [verification needed] Cramer's rule can also be numerically unstable even for 2×2 systems. [10] However, Cramer's rule can be implemented with the same complexity as Gaussian elimination, [11] [12] (consistently requires twice as many arithmetic operations and has the same numerical stability when the same permutation matrices are ...
Jason Fitz, Charles Robinson & Frank Schwab look at what a path to fixing the Dallas Cowboys would look like and recap the Thursday Night Football game between the Philadelphia Eagles and ...
Secondary School Certificate is a public exam for classes 9 and 10 separately. Class 9 exam is called SSC part-1 and class 10 exam is called SSC part-2. This exam is conducted by government boards, officially known as Boards of Intermediate and Secondary Education, or simply BISE.
