| 单词 | tangency |
| 释义 | tangency A situation where two smooth curves touch but do not cross. For two curves y = f(x) and z = g(x) to be tangential at x = x*, it is a necessary condition that f(x*) = g(x*) and dy/dx = dz/dx when both functions are evaluated at x = x*, and it is a sufficient condition that d2 y/dx2 ≠ d2 z/dx2. Thus the two curves both pass through one point at x = x*: they have the same slope but different curvature. |
