What Does the Dot Product Mean?

The scalar product, or dot product, is another name for it in mathematics. The scalar amount that results from certain operations performed on the vector components is known as the dot product. The heavy dot is used to symbolize the dot product of two vectors. To determine if the two vectors are orthogonal or not, use the dot product. The formula for calculating the dot product of two vectors, given a and b, is as follows:

As |a| × |b| × cos(θ), a · b =

What Formula Does the Dot Product Use?

Assume for the moment that we will do all of our computations in three dimensions. This implies that three elements can be used to represent any vector:

a = [a₁, a₂, a₃]

B is equal to [b₁, b₂, b₃].

Geometrically speaking, the dot product can be defined as the product of the magnitudes of the vectors and the cosine of the angle that separates them. This can be stated using the following equation:

Geometrically speaking, the dot product can be defined as the product of the magnitudes of the vectors and the cosine of the angle that separates them. This can be stated using the following equation:

a·b = cos α * |a| * |b|

Visit the unit vector calculator for additional information if you’re unsure about how to determine or what a vector’s magnitude is.

It should be evident to you that the scalar product, independent of the vector magnitudes, will always equal zero if the angle between two vectors is 90°. 

Similarly, multiplying the multitudes alone yields the dot product if the angle is equal to 0° (i.e., the vectors are collinear). Put another way, the dot product value increases with the size of the relative slope between two vectors. The slope calculator can be used to determine a vector’s slope.

How to calculate the vector dot product?

So how does our calculator for vector multiplication operate? To gain a better understanding of the principle underlying this method, follow this example step by step.

  • Select vector a. We’ll pick a = [4, 5, -3] as an example.
  • Select vector b. Assume for the moment that it equals b = [1, -2, -2].
  • Determine each vector’s product by multiplying its first component. This time, the answer is 4 * 1 = 4.
  • Determine each vector’s product by multiplying its second (middle) component. It is equivalent to 5 * (-2) = -10 in this instance.
  • Determine each vector’s product of its third component. This time, the answer is (-3) * (-2) = 6.
  • To determine the dot product of the vectors a and b, add all of these findings together.

(-10) + 6 + 4 = 0.

The outcome is zero. The scalar product of these two vectors yields this result. It indicates that they are 90° angles apart and perpendicular to one another.

Conclusion
