Consider the two vectors a with arrow = 3 î − ĵ and b with arrow = − î − 2 ĵ. (a) calculate a with arrow + b with arrow 2 correct: your answer is correct. î + -3 correct: your answer is correct. ĵ (b) calculate a with arrow − b with arrow 4 correct: your answer is correct. î + 1 correct: your answer is correct. ĵ (c) calculate a with arrow + b with arrow (d) calculate a with arrow − b with arrow (e) calculate the directions of a with arrow + b with arrow and a with arrow − b with arrow. a with arrow + b with arrow incorrect: your answer is incorrect. note that tan (θ + 180°) = tan θ so the inverse tangent should give two answers. your calculator only provides one, so you must draw a careful picture of this vector to check your calculator value.° (counterclockwise from the +x axis) a with arrow − b with arrow ° (counterclockwise from the +x axis)
