Coding in Matlab - Dot, cross, and triple products
In matlab, scaler product is defined as "dot", the cross product is defined as "cross". Hence, to compute the triple product directly in matlab is:
dot(x,cross(y,z));.

Addition vector of two velocities
The direction vectors i and j are orthonormal meaning that they are orthogonal such that they are perpendicular to one another and that the dot product of identical vectors is unity or 1.

Decomposition of a vector.
The projection is found as
Proj_W (V) = [(V dot W)/(W dot W)] times W
The dot here represents the dot product of two vectors, so it's a number.

Work, vectors, and the inner product
If the vectors A and B have magnitudes of 10 and 11, respectively, and the scalar product of these two vectors is -100, what is the magnitude of the sum of these two vectors?
6. Two vectors A and B are given by A = 4i + 8j and B = 6i - 2j.

Finding dot product of vectors.
47523 Vectors Using the given vectors how do I find the specified dot product u=3i-8j;v=4i+9j find u.v The vectors are U = 3 i - 8j and V = 4i + 9j
U.V = (3i - 8j) . (4i+9j)
= 3*4 (i.i) + 3*9 (i.j) - 8*4 (j.i) - 8*9 (j.j)
Now recall that i.i

Vectors : Identities and Dot Products
24523 Vectors: Identities and Dot Products How could you use the properties of the dot product to prove the following identities: (where u and v denote vectors in Rn)
a) ||u + v||^2 + ||u-v||^2 = 2(||u||^2 + ||v||^2)
b) ||u + v||^2 - ||u-v||^2 = 4u
