In mathematics physics and engineering a Euclidean vector (sometimes called a geometric or spatial vector oras heresimply a vector) is a geometric object that has magnitude (or graphicgth) and direction.Vectors can be added to other vectors according to vector algebra.A Euclidean vector is frequently represented by a line segment with a definite direction or graphically as an In mathematics the dot product or scalar product is an algebraic operation that takes two equal-graphicgth sequences of numbers (usually coordinate vectors) and returns a single number.In Euclidean geometry the dot product of the Cartesian coordinates of two vectors is widely used and often called inner product (or rarely projection product) see also inner product graphice.where denotes a dot product denotes a cross product denotes a determinant and and are components of the vectors and respectively.The scalar triple product is a pseudoscalar (i.e. it reverses sign under inversion). The scalar triple product can also be written in terms of the permutation symbol as

Dot Product A vector has magnitude (how long it is) and direction. Here are two vectors They can be multiplied using the Dot Product (also see Cross Product).. Calculating. The Dot Product gives a number as an answer (a scalar not a vector).. The Dot Product is written using a central dot a b This means the Dot Product of a and b . We can calculate the Dot Product of two vectors Which Direction The cross product could point in the completely opposite direction and still be at right angles to the two other vectors so we have theVectors. Components. Vector addition and subtraction. Scalar product and vector product (dot product and cross product). Displacement velocity and acceleration.

Click on Submit (the arrow to the right of the problem) and scroll down to Find the Angle Between the Vectors to solve this problem. You can also type in more problems or click on the 3 dots in the upper right hand corner to drill down for example problems.where is the angle between the vectors and is the norm.It follows immediately that if is perpendicular to .The dot product therefore has the geometric interpretation as the graphicgth of the projection of onto the unit vector when the two vectors Vector Dot Product. We can calculate the sum of the multiplied elements of two vectors of the same graphicgth to give a scalar. This is called the dot product named because of the dot operator used when describing the operation.
