A dihedral angle is defined as the angle between two planes, both of which pass through the same bond. From:Encyclopedia of Physical Science and Technology (Third Edition),2003 About this page Add to MendeleySet alert On this page Definition ...
It is the angle between the velocity vector, v→, and the line-of-sight vector, u→ (unit vector of the radar-to-target axis). θB is the bearing angle. It is the projection of the azimuth angle on the horizontal plane. θB and θA are identical when the depression angle is ...
planes [两个平面相交]. These are called dihedral angles. Two intersecting curves define also an angle, which is the angle of the tangents [切线] at the intersection point. For example, the spherical angle [球面角] formed by two great circles on a sphere equals the dihedral angle between ...
Find the (acute) angle theta between the planes x + \sqrt3 z = 3 and -3/4 x + \sqrt3 / 2 y - 3\sqrt3/ 4 z = 4. How do I calculate the size of an exterior angle in regular polygons with 45 sides? What is the sum of the interior angles of a 20-gon?
