An important element is the use of lexical conceptual paradigms (lcp), shorthand notations for sets of possible interpretations. Shorthand notations include tildes and straight lines placed above or below the name of a vector. From Wikipedia

= magnitude of vector b \(\begin{array}{l}\left | \vec{b} \right |=\sqrt{b_x^2+b_y^2+b_z^2}\end{array} \) cosine of angle between two vectors the formula for finding cosine of angle between two vectors can be deduced by the formula of angle between two vectors \(\begin{...
fields and Maxwell's equations are the four equations that describe how these fields act and how they are related to each other. Maxwell's complicated equations are rendered stunningly simple and beautiful when written in differential forms notation instead of the usual vector calculus notation.doi...

回顾最前面的Mathematical Notation: A superscript T denotes the transpose of a matrix or vector, so that xTwill be a row vector. Uppercase bold roman letters, such as M, denote matrices. The notation (w1, . . . , wM) denotes a row vector with M elements, while the corresponding column...
The scalar product of two vectors is given by the product of the magnitude of both vector into cosine of the angle between them, Mathematically {eq}\begin{align} \vec{A}.\vec{B} = AB \cos \theta \end{align} {/eq} WhereA...
Figure 1.6.3(b) shows the skew lines, points A and B, the blue vector V=B−A=573−326=25−3 from A to B, and N, in green. • The distance between the lines is V·N/N=16/11 the scalar projection ofVonN. ...
Mathematical Solution Start with the general polar vector fieldF=fr,θer+gr,θeθ. Change this to Cartesian coordinates in which the expression for the divergence is known. Then restore polar coordinates. Using the results of Example 9.2.13, the Cartesian form forFis th...
