4. Find the angle between a = 2ˆ ex + 3ˆ ˆy − 6ˆ ez and b = 4ˆ ex − 6ˆ ey + 5ˆ ez . 5. 6. Show that a = e vectors in the xy-plane making angles α and β with the x-axis. Then take their dot product and obtain a formula for cos(α−β). Now use sin x = cos(π/2−x) to ﬁnd the formula for sin(α − β). 7. Vectors a and b are the sides of a parallelogram, c and d are its diagonals, and θ is the angle between a and b. Show that |c|2 + |d|2 = 2(|a|2 + |b|2 ) and that |c|2 − |d|2 = 4|a| |b| cos θ. 8. Given a, b, and c—vectors from the origin to the points A, B, and C— show that the vector (a × b) + (b × c) + (c × a) is perpendicular to the plane ABC.
2 + z 2 )3/2 (ρ + z 2 )3/2 Since r gives the position of a point in space, one can use it to write the distance between two points P1 and P2 with position vectors r1 and r2 . 15 shows that r2 − r1 is the displacement vector from P1 to P2 . The importance of this vector stems from the fact that many physical quantities are functions of distances between point particles, and r2 − r1 is a concise way of expressing this distance. The following example illustrates this. Historical Notes During the second half of the eighteenth century many physicists were engaged in a quantitative study of electricity and magnetism.
22) expresses Fq in spherical coordinates. Thus, its components in terms of unit vectors at q are ke qq /r 2 , 0, 0 . 22). Noting that e Fq = ke qq ke qq r = r. 12) to obtain r 3 = (x2 +y 2 +z 2 )3/2 . 23) yields Fq = ke qq (xˆ ex + yˆ ey + zˆ ez ). 23), we obtain Fq = ke qq ˆρ + zˆ (ρ e ez ). (ρ2 + z 2 )3/2 . 15: The displacement vector between P1 and P2 is the diﬀerence between their position vectors. Thus the components of Fq along the cylindrical unit vectors constructed at the location of q are ke qq z ke qq ρ , 0, 2 .
