Question
Consider the two vectors A vector = 5 i^- j^and B vector = i^- 2 j^. (a) Calculate A vector + B vector (b) Calculate A vector - B vector (c) Calculate |A vector + B vector| (d) Calculate |A vector - B vector| (e) Calculate the directions of A vector + B vector and A vector - B vector. A vector + B vector Note that tan (theta + 180 degree) = tan theta so the inverse tangent should give must draw a careful picture of this vector to check your calculator A vector - B vector Note that tan (theta + 180 degree) = tan theta so the inverse tangent should must draw a careful picture bf this vector to check your calculatorExplanation / Answer
e) for the direction of A + B
A+ B = 4 i - 3 j
as it lies in the forth quadrant
direction of A + B = 360 - arctan(3/4)
direction of A + B = 323.13 degree
A - B = 6 i + j
as this lies in the first quadrant
direction of A - B = arctan(1/6)
direction of A - B = 9.46 degree
