2D Vector Operations. For problem 3 use the following values for vectors "A" and "B" A = 1.2 mi + 2.7 m j B = 3.2 mi + 2.1 m ) Note that the direction angles are measured with respect to the positive x-axis (as is standard in Trigonometry). 3) Calculate: A) A + B B) 3 A + 4B= C) 2 A - 3B = D) | | A| = E) direction angle "0A" of vector "A": Page 4 of 10
