Perpendicular Position Vectors - Ask Question Asked 12 years, 6 months ago Modified 3 years ago Moreover if I want create a triple of orthogonal vectors in $\mathbb R^3$, cross product is still a very efficent way to find the third perpendicular vector in the triple. Two vectors are perpendicular (also called orthogonal) when their dot product equals zero. We may need to find the position vectors of P and Q rather than the distance between them. 10. To show that the triangle is a right triangle, it is enough to prove that the two of its sides are perpendicular. Alternate names for this are the normal vector or orthogonal vector. 5 Products of vectors The 'algebra' of vectors has been developed in previous sections. In 3D space there are infinitely many vectors perpendicular to V1! What you want to find is either one arbitrary V2 (perp to V1) or you want to detect if (V1,V2) are perpendicular. How to find the position vector for the point of intersection of a line and the perpendicular line through a point C Ask Question Asked 5 years, 8 months ago Modified 5 years, 8 Coordinate syatems Two systems are in use for specifying position vectors: a distance and bearing, and components specified in two perpendicular directions.
