Description

technical field [0001] The invention relates to a measuring device, in particular to an auxiliary device for measuring the circumference of a cylinder in high school mathematics. Background technique [0002] Mathematics is a discipline that studies concepts such as quantity, structure, change, space, and information. From a certain perspective, it is a kind of formal science. In the development of human history and social life, mathematics also plays an irreplaceable role, and it is also an indispensable basic tool for learning and researching modern science and technology. [0003] Cylinder: There is a fixed line and a moving line in the same plane. When the plane rotates around the fixed line, the surface formed by the moving line is called the rotation surface, and the fixed line is called the axis of the rotation surface. , this moving line is called the generatrix of the plane of revolution. If two planes perpendicular to the axis are used to cut the cylindrical surf...
