Solve

Let i, j and k denote the standard basis vectors of RS. Let u = 37 - 3j - 3k and v = i - 2j - k. a) Calculate the following orthogonal projection: proju (u) = FORMATTING: Write your answer in the form Ai + Bj + Ck. eg, 3i + 2k or (2i + 3j - 5k) /4. Do not put arrows on the vectors i, j and k b) What is the angle (in radians) between u and ? D Number rad FORMATTING: Round your answer to 2 decimal places
