A from U to V is a function T: Uâf V, such that T(u_1 + u_2) = T(u_1) + T(u_2), for u_1,u_2 â~U, and T(î±u) = î±T(u) for î±â~ F and U â~ U. Answer: Linear transformations Question: Any element from the set of real numbers is also called a Answer: Scalar Question: A diagonal matrix having equal elements is called a Answer: Identical matrice Question: If a matrix â€~A’ has â€~m’ number of columns and â€~n’ number of rows then m Ä— n is said to be Answer: Order of a matrix Question: Consider the vector space U over a field F, and the function T:UâfU defined by T(u) = u for all u â~ U. This transformation is called the Answer: Identity transformation Question: Matrix multiplication is genrally not Answer: commutative Question: â€| is the study of certain mappings between two vector spaces. Answer: Linear transformations Question: If A(BC) = (AB)C, then with respect to multilpication this law is called Answer: Associative law Question: If the transpose of A is -A, then A is said to be Answer: Skew symmetric Email: bbcnoun@gmail.com Whatsapp: 08131667008
