How to find a scalar product?
Understand the Problem
The question is asking for the method to calculate the scalar product, also known as the dot product, of two vectors. This generally involves multiplying corresponding components of the vectors and summing the results.
Answer
a · b = |a||b| cos(θ)
The scalar product of two vectors a and b is given by: a · b = |a||b| cos(θ)
Answer for screen readers
The scalar product of two vectors a and b is given by: a · b = |a||b| cos(θ)
More Information
The scalar product (or dot product) is fundamental in vector algebra and has applications in physics, engineering, and computer science.
Tips
A common mistake is not ensuring that the angle θ used is the correct angle between the vectors.
