Here, The dot product of two vectors a= and b= is given by An equivalent definition of the dot product is where theta is the angle between the two vectors (see the figure below) and |c| denotes the magnitude of the vector c. This second definition is useful for finding the angle theta between the two vectors. Complex Numbers. Polynomials . The dot product is a method to multiply two vectors that results in a scalar. So, the two vectors are orthogonal.

Multiplying Polynomials Division of Polynomials Zeros of … The formula for the dot product in terms of vector components would make it easier to calculate the dot product between two given vectors. Dot product: Apply the directional growth of one vector to another. Let's work through some problems utilizing the dot product. Getting the Formula Out of the Way. Let u and v be two vectors in a plane. This formula gives a clear picture on the properties of the dot product. The dot product is also known as Scalar product. Algebra . Reminder (see the lessons Dot-product of vectors and the angle between two vectors in this site). Roots and Radicals. The result is how much stronger we've made the original vector (positive, negative, or zero). Arithmetic Polar representation.
