Finding the Orthogonal Projection from a Matrix where $ a_ij = vec v_icdot vec v_j$ Announcing the arrival of Valued Associate #679: Cesar Manara Planned maintenance scheduled April 17/18, 2019 at 00:00UTC (8:00pm US/Eastern)A question about subspacesEntries of a positive definite symmetric matrix as inner productsGoing from an arbitrary basis $mathbbB_u$ to an ON-basis $mathbbB_v$ in $mathbbR^3$Find orthonormal basis of $mathbbR^3$ with a given span of two basis vectorsName of outer “product” of two vectors with exponentiation instead of multiplicationFind the maximum possible $k$ s.t. $langle v_i,v_jrangleleq 0$ for all $ineq j$.If I have a diagonalized matrix with degenerate eigenvalues, how do I generate an orthonormal set of vectors?why is $ vec u bullet vec v = u_1v_1 + u_2v_2$?Prove that every $3$ of $ 4$ vectors of $2$- planes are linearly independent.Form of a matrix in a basis where some of the basis vectors are eigenvectors
