Vectors
Let vectors $$\bar{A} =(2,1,-4), \bar{B} =(-3,0,1), \text{ and } \bar{C} =(-1,-1,2)$$
Calculate the following:
A)$$\bar{A} \cdot \bar{B}$$?
E)Which of the following can be computed?
$$\bar{A} \cdot \bar{B} \cdot \bar{C}$$
$$\bar{A}(\bar{B} \cdot \bar{C})$$
$$\bar{A}(\bar{B} + \bar{C})$$
$$3\bar{A}$$
F)Express your answer in terms of $$v_1$$
G) If $$v_1 \text{ and } v_2$$ are perpendicular?
H) If $$v_1 \text{ and } v_2$$ are parallel?
