Consider the lines (x,y,z) = (4,7,-1) + t(4,8,-4) and (x,y,z) = (1,5,4) + s(-1,2,3). a) Show that the lines intersect at the right angle. b) Find the point of intersection. Find the point of intersec...
Why don't two magnetic field lines intersect? Why is the clearest vision at the central fovea? Why is a stereomicroscope also called a binocular dissecting microscope? Why can the human eye only see visible light? Why are the semicircular canals at right angles?
This paper proposed two accurate and automatic methods to measure the NSA based on a 2D plane and a 3D model respectively. Although the femoral neck and femoral shaft axes did not intersect in 3D space, the NSAs obtained by 2D and 3D methods were basically consistent....
The second sensor element may further comprise a first main trace and a second main trace, where the first main trace and the second main trace intersect each of the first plurality of sensor elements, and where each of the main traces cross at least one of a plurality of unit cells ...
