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

चरण-दर-चरण मार्गदर्शिका

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

हल किए गए उदाहरण

इनपुट
a=(3,4), b=(1,0)
परिणाम
Scalar proj = 3, vector proj = (3,0)

सामान्य गलतियां जिनसे बचना है

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

अक्सर पूछे जाने वाले प्रश्न

How is this different from dot product?

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