To show that the points A(a,b+c), B(b,c+a), and C(c,a+b) are collinear, we can use the concept of the area of the triangle formed by these three points. If the area of the triangle is zero, then the points are collinear. Step 1: Set up the determinant The area A of ...
Show that three points P, Q, and R are collinear (lie on a line) if and only if \vec{PQ} \times \vec{PR} = \vec{0} Show that the following points taken in order form the vertices of a parallelogram. (-7, -5), (-4, 3), (5, 6) and (2, ...
Determine if the vectors \vec u = [3, -9, 15] and \vec v = - \vec i + 3\vec j - 5 \vec k are collinear. Prove the equation for the given vectors. Show that \vec{a}\times(\vec{b}\times\vec{c})...
Suppose that P, Q, and R are three noncollinear points. Show that there are three points A, B, and C, any one of which together with P, Q, and R forms a parallelogram. Show that (OA)+ (OB)+ (OC)= (OP)+ (OQ)+ (OR) 相关知识点: ...
“Panama”). The combination of eliminated and retained metabolic pathways of the bacterium indicates a potential for a mutualistic as well as for a parasitic relationship, whose outcome could depend on the environmental context. In particular we show that the endosymbiont is dependent on the host ...
noncollinear gradient directions with a single b-value shell at 1000 sm−2. Group comparisons were carried out using Tract-Based Spatial Statistics (TBSS)17available in FMRIB Software Library (FSL), with a randomise function allowing voxel-wise nonparametric permutation analysis of the DTI maps...
aThis seems to show that the reach of the contrast polarity signal inside the association field of a contour unit is shorter along non-collinear orientations than along collinear ones. 这似乎表示,对比极性信号的伸手可及的距离在等高单位里面的协会领域沿非在同一直线上取向是短比沿在同一直线上那些。
