Hi. I have the following 2 questions. 1. Find a vector that, together with vectors [1,1,1], and [1,2,1], forms a basis of R^3. 2. Show that the functions (c1 + c2sin^2x + c3cos^2x) form a vector space. Find a basis for it. What is its dimension? Thanks

V3(R) represents the set of vectors in 3D space. What kind of geometrical objects are represented by the various subspaces of V3(R)? i.e A 1D subspace S with basis { (0, 1, 0)Transpose} represents the set of vectors parallel to the y-axis, so the set of points with position vectors in s is the y-axis itself.
