 Dot product
In mathematics, the dot product is a binary operation which takes two vectors and returns a scalar quantity.
If a and b are both unit vectors (ie of length 1), the the dot product simply gives the cosine of the angle between them.
The dot product is particularly used in resolution of forces[?].

 Symmetric Bilinear Form -- from Wolfram MathWorld
For other fields, there are more symmetric bilinear forms than in the real or complex case.
Two symmetric bilinear forms are considered equivalent if a change of basis takes one to the other.
Therefore, the rank of the symmetric bilinear form is an invariant.

The inner product is bilinear, so have a chance of talking about it in the doctrine of monoidal categories.
An algebra with a nondegenerate bilinear form having this property is called a "composition algebra".
I think you can summarize his theorem on vector product algebras as follows: in all symmetric monoidal R-linear categories where R is a commutative ring containing Z[1/2] and I is a simple object, vector product algebras must have dimension 0, 1, 3, or 7.

 Dot Product
Sometimes an appropriate inner product, or dot product, is defined.
When scalars are taken from the field of real numbers, the "standard" dot product of two vectors is the sum of the products of the corresponding entries.
Their dot product, divided by n, approximates the integral of fg.

 Induced inner product
if v1,...vn, and w1,...wm are bases of V and W, then the bilinear functions taking (vi,wj) to 1 and the other pairs to zero, form a basis of the dual of the tensor product.
We'll define the inner product of v(tens)w with u(tens)x as .
This induces an inner product on all of V(tens)W, since the inner product must be bilinear.

 ccmm97 abstract: Cai and Douglas   (Site not responding. Last check: 2007-10-09)
While existing results indicate that such methods have great promise, a fast solver for the resulting algebraic equations has been missing for many such methods, possibly because of a too simple treatment of the perturbation term and the lack of symmetry of the schemes.
The effect of the former is that the bilinear form is either not elliptic or not continuous with respect to norms separating velocity and pressure.
Our bilinear form is then elliptic and continuous with respect to the $H^1$-norm for the velocity and the $L^2$-norm for the pressure, and an error estimate of the finite element approximation follows immediately.

In fact what you're doing there is constructing the wedge product of the other base vectors, so as to use it as a covector.
this vector product is bilinear (as all products must be), but neither commutative nor associative.
It may be right that the stroy is not real and that the use of that notation originated it, as I said, I'm not 100% sure about it and I haven't got the chance to confirm it with serious sources.

Bilinear means linear in each input, if you hold the other input constant.
For less straightforward spaces the inner product is even used to define notions such as "length" and "orthogonality".

This book provides you with a single source of information on the problem of coherent-mode representations in optics, including new perspectives on its potential applications.
In particular, the "light string" and the "light capillary" beams may be advantageously used in communications, measurements, laser microtechnology, and microsurgery; application of the fast algorithm for bilinear transforms can significantly reduce the computer effort needed to simulate optical systems with partially coherent illumination.
Perhaps, the coherent-mode representation of the optical field broached for the first time by H. Gamo in his Matrix Treatment of Partial Coherence (Progress in Optics III, E.
