Functions can be thought of as elements of a vector space. When we have two functions, we will make a 2x2 matrix of functions here the first row is the original functions and the second row are the first derivatives of the original functions. With three functions, we have two more rows, the first derivatives in row two and the second derivatives in row three. The matrix form is called the Wronskian. If you take the determinant and it is...

Orthogonal projections. In class we showed that if V is a finite-dimensional inner product space and U-V s a subspace, then U㊥ U↓-V, (U 1-U, and Pb is well-defined Inspecting the proofs, convince yourself that all that was needed was for U to be finite- dimensional. (In fact, your book does it this way). Then answer the following questions (a) Let V be an inner product space. Prove that for any u V. if u 0, we have proj, Pspan(v)...
