Please solve this and provide a step-by-step solution how you got the answer. No. 4 consists of FOUR parts please read the questions carefully. Thanks!

4. Given two vectors and A = 41 + 7j and B = 51 - 2j (a) find the magnitude of each vector; (b) write an expression for the vector difference A - B using unit vectors; (c) find the magnitude and direction of the vector difference A - B (d) In a vector diagram show A, B and A - B and also show that your diagram agrees qualitatively with your answer in part (c). 5. Find the angle between each of the following pairs of vectors: (a) A = -2.001 + 6.00} and B = 2.001 - 3.00j (b) A = 3.007 + 5.00j and B = 10.001 + 6.00j
