Projections, Finally Explained Conceptually

f vector projections never really made sense, this is the explanation I wish I’d had as a student. Scalar vs vector vs orthogonal projections — explained geometrically, not just as formulas.

Vector Projections

Vector Dot product: Important technique To find angle between two vectors #vectors

Q) Let 𝑎 ⃗=2𝑖+𝑗−𝑘, 𝑏 ⃗=((𝑎 ⃗×(𝑖+𝑗))×𝑖)×𝑖 Then the square of the projection of 𝑎 ⃗ on
