Dot Product of Two Vectors is obtained by multiplying the magnitudes of the vectors and the cos angle between them. Click now to learn about the dot product of vectors properties and formulas with example questions.
And the result is a number (called a "scalar" to show it is not a vector).Example: Calculate the dot product of vectors a and b: a· b = |a|× |b|× cos(θ) a· b = 10 × 13 × cos(59.5°) a· b = 10 × 13 × 0.5075... a· b = 65.98... = 66 (rounded) OR...

Vector dot product represents a scalar value. As an algebraic number, the dot product of two vectors relates to the magnitudes of the two vectors and the angle between them. For example, the dot vector of force and its displacement given the work done by the force on that distance. What ...
Example 3.Find the dot product of vectorsp=a+ 3bandq= 5a- 3b, if their magnitudes is |a| = 3, |b| = 2, and the angle between the vectorsaandbis equal to 60˚. Solution: p·q= (a+ 3b) · (5a- 3b) = 5a·a- 3a·b+ 15b·a- 9b·b= ...

Elementwise product. Another common operation we see in practice is the elementwise product. You often may want to operate on each element of a vector while doing a computation. For example, you may want to add two matrices of the same dimensions by adding all of the corresponding elements ...
