Final answer:
The scalar projection of b onto a can be found using the formula: Scalar projection of b onto a = |b| * cos(θ), where |b| is the magnitude of vector b and cos(θ) is the cosine of the angle between vectors a and b. To find θ, you can use the formula: cos(θ) = (a · b) / (|a| · |b|).
Step-by-step explanation:
The scalar projection of b onto a can be found using the formula:
Scalar projection of b onto a = |b| * cos(θ)
where |b| is the magnitude of vector b and cos(θ) is the cosine of the angle between vectors a and b.
To find θ, you can use the formula:
cos(θ) = (a · b) / (|a| ⋅ |b|)
where (a · b) is the dot product of vectors a and b and |a| and |b| are the magnitudes of vectors a and b respectively.
