AI Thread Summary
The notation "compab" refers to the scalar projection of vector b onto vector a. It represents the magnitude of vector b in the direction of vector a. The formula for computing this projection is (a*b)/|a|, where a*b is the dot product of vectors a and b, and |a| is the magnitude of vector a. This concept is essential in vector calculus and helps in understanding projections in multidimensional spaces. The discussion clarifies the meaning and calculation method for this specific notation.
