Line intersection finds where two lines meet in 2D or 3D space; useful in geometry and computer graphics.
Trin-for-trin guide
- 1Input two lines (parametric or standard form)
- 2Solve system of equations
- 3Find intersection point or determine parallel/skew
Løste eksempler
Input
Line 1: y=2x+1, Line 2: y=-x+4
Resultat
Intersection: (1, 3)
Almindelige fejl at undgå
- ✕Confusing parametric with standard form
- ✕Not handling 3D case (skew possible)
Ofte stillede spørgsmål
What if lines don't intersect?
Parallel (same slope) or skew in 3D (no intersection).
