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 Correc
t: 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)
