12、Then, if I choose anyvectorin that tangent plane.(那么如果我选择了任何位于切平面的向量。) 13、I experience avectorquantity.(我经历了一个矢量的量变。) 14、An expressingvectorof major outer-membrane protein of Chlamydia psittaci was constructed.(构建了鹦鹉热衣原体主要外膜蛋白的表达载体。) ...
T = unit tangent \Rightarrow{T}=-yi+xj (on the unit circle x^{2}+y^{2}=1 ). \Rightarrow{F}\cdot{T}=y^{2}+x^{2}=1 (on the unit circle) \Rightarrow{I}=\int_{c}ds=arclength\ of\ circle=2\pi. Lesson: it can pay to think geometrically. Another way to understand them...
Dear Grasshopper users; I must assign tangent vectors or perpendicular planes at any given point of the curve. However, points are not assigned with regular intervals and i cannot assure if the curve is planar tip to toe. My only input will be the point and the curve. Thanks & Regards Ch...
