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.
