here,
u = 3 i + 4 j
v = - 3 i + 2 j - 5 k
4)
the magnitude of u , |u| = sqrt(3^2 + 4^2)
|u| = 5 units
the magnitude of v , |v| = sqrt(3^2 + 2^2 + 5^2)
|v| = 6.16 units
the angle between u and v , theta = arccos((u.v)/(|u|*|v|))
theta = arccos((3 * (-3) + 4 * 2)/(5 * 6.16))
theta = 91.86 degree
the angle between the vectors is 91.86 degree
5)
u X v = (3 i + 4 j) X ( - 3 i + 3 j - 5 k)
u X v = ( 3 * 3 k + 3 * 5 j + 4 * 3 k - 4 * 5 i)
u X v = ( - 20 i + 15 j + 21 k)

4. Vectors The angle of the vector could be given measured from either axis (and not necessarily fr positive x or y axis). How you break the vector into its components depends on where an angle i measured from. Suppose that we know the angle of the vector A relative to the y-axis, as shown (where the angle is now labeled as p). Ax Ay 4.11. When the angle (p)is measured from the y-axis, as above, what are Ax and...
