In mathematics and vector algebra the cross product or vector product (occasionally directed area product to emphasize the geometric significance) is a binary operation on two vectors in three-dimensional vectore (R 3) and is denoted by the symbol .The scalar projection (or scalar component) of a Euclidean vector a in the direction of a Euclidean vector b is given by where is the angle between a and b.. In terms of the geometric definition of the dot product this can be rewrittenwhere is the angle between the vectors v and w.This formula is used extensively in computer graphics since it speeds up computation in many situations by avoiding direct usage of an inefficient trigonometric function.

Discussion scalar-vector multiplication. Multiplication of a vector by a scalar changes the magnitude of the vector but leaves its direction unchanged.This can be a really tough one and to be honest I dont find many of the vectorogies very useful. Im a vector game programmer so I need the dot product a lot and I still find it easiest to think in terms of projection as sterile as it may sound.The gradient is a fancy word for derivative or the rate of change of a function. Its a vector (a direction to move) that Points in the direction of greatest increase of a function (intuition on why) Is zero at a local maximum or local minimum (because there is no single direction of increase
