For each statement, decide whether it is always true (T) or sometimes false (F) and write your answer clearly next to the letter before the statement. In this question, u and v are non-zero vectors in R"; W is a vector space, wi is a vector in W, and P2 is the vector space of polynomials of degree less than or equal to 2 with real coefficients.
