Soli pa solim ceļvedis
- 1Input two vectors
- 2Calculate scalar projection: (a·b)/|b|
- 3Results show vector projection and scalar
Worked Examples
Ievade
a=(3,4), b=(1,0)
Rezultāts
Scalar proj = 3, vector proj = (3,0)
Common Mistakes to Avoid
- ✕Using dot product alone (missing direction)
- ✕Not normalizing vector b
Frequently Asked Questions
How is this different from dot product?
Dot product gives scalar; projection gives vector in b's direction.
