{(; ?)· (: :)· (; )} 1 Consider the ordered basis B for the the set of symmetric -1 2 x 2 matrices with entries in R. Given that [G ). 1 2 (а, ь, с)", find the value of c. (Note: The question is asking you for only the value of c. Your answer should therefore be just one number.)

Branch of mathematics concerned with mathematical structures that are closed under operations like addition and scalar multiplication. It is the study of linear combinations, vector spaces, lines and planes, and some mappings that are used to perform linear transformations. Linear algebra also includes vectors, matrices, and linear functions. It has many applications from mathematical physics to modern algebra and coding theory.
