Curve tangent normal binormal
WebDec 29, 2024 · Figure 11.4.5: Plotting unit tangent and normal vectors in Example 11.4.4. The final result for ⇀ N(t) in Example 11.4.4 is suspiciously similar to ⇀ T(t). There is a clear reason for this. If ⇀ u = u1, u2 is a unit vector in R2, then the only unit vectors orthogonal to ⇀ u are − u2, u1 and u2, − u1 . WebTHE NORMAL AND BINORMAL VECTORS 7 Figure 3: Definition 0.10 (The binormal vector) Let C be a regular curve described by the vector function ⃗ r: [a, b] → R 3 . The binormal vector to the curve C at ⃗ r ( t ) is defined as ⃗ B ( t ) := ⃗ T ( t ) × ⃗ N ( t ) .
