Prob 4. Show that the operator T = —D2 is nonnegative on the space V :=span(1, cos cc,sin:c) over IR,with the inner product (f, g) := :f(x)g(m)dm.Find(a) its square root operator x/i(b) an example of a self—adjoint operator R 7E x/T such that R2 2 T; (c) an example of a non—self—adjoint operator 8 such that 8*8' = T.
