WebIn a unit circle, the speed of rotation is the same as the actual speed, because the length of the circumference is the same as one full rotation in radians (both are 2 π). The radius of the ISS orbit is 6800 km, which means that the actual speed of the ISS has to be 2 π 1.5 × 6800 2 π 1.5 ÷ 6800 6800 2 · π = 28483 km per hour. In calculus and most other branches of mathematics beyond practical geometry, angles are measured in radians. This is because radians have a mathematical naturalness that leads to a more elegant formulation of some important results. Results in analysis involving trigonometric functions can be elegantly stated when the functions' arguments are expressed in radians. For example, the use of ra…
