2.4.3 Find a vector orthogonal to two given vectors. 2.4.4 Determine areas and volumes by using the cross product. 2.4.5 Calculate the torque of a given force and position vector. Imagine a mechanic turning a wrench to tighten a bolt. The mechanic applies a force at the end of the wrench. ... = 〈 u 1, u 2, u 3 〉 · 〈 u 2 v 3 − u 3 v 2 ...
29 gru 2020 · The cross product of →u and →v, denoted →u × →v, is the vector. →u × →v = u2v3 − u3v2, − (u1v3 − u3v1), u1v2 − u2v1 . This definition can be a bit cumbersome to remember. After an example we will give a convenient method for computing the cross product.
To find the volume of the parallelepiped spanned by three vectors u, v, and w, we find the triple product: Volume = u . (v x w) This can be found by computing the determinate of the three vectors: Example. Find the volume of the parallelepiped spanned by the vectors. u = <1,0,2> v = <0,2,3> w = <0,1,3>. Solution.
The previous section introduced vectors and described how to add them together and how to multiply them by scalars. This section introduces a multiplication on vectors called the dot product. Definition 11.3.1 Dot Product. (a) Let u → = u 1, u 2 and v → = v 1, v 2 in ℝ 2.
