Vector projection (proj_b a) shows component of vector a in direction of vector b; used in physics, graphics.

ଷ୍ଟେପ୍-ଷ୍ଟେପ୍ ଗାଇଡ୍ |

  1. 1Input two vectors
  2. 2Calculate scalar projection: (a·b)/|b|
  3. 3Results show vector projection and scalar

ସମାଧାନ ହୋଇଥିବା ଉଦାହରଣ

ଇନପୁଟ୍
a=(3,4), b=(1,0)
ଫଳ
Scalar proj = 3, vector proj = (3,0)

ଏଡ଼ାଇବା ଯୋଗ୍ୟ ସାଧାରଣ ଭୁଲ

  • Using dot product alone (missing direction)
  • Not normalizing vector b

How is this different from dot product?

Dot product gives scalar; projection gives vector in b's direction.
