I have trouble to understand what does it mean restrictions in Calculus: Integral with adjustable bounds sheet (https://www.desmos.com/calculator/u2qz73ufju) we can find this 0<=y<=f(x) {(a-x)(b-x)<0} I don't understand this restriction {(a-x)(b-x)<0} can you help me please ? best regards
Sacrificial anodes are pieces of metal attached to. the UST system that are more electrically active. than the steel UST system. Because these. anodes are more active, the corrosive current. will exit from them rather than the UST system. Thus, the UST system is protected while the. attached anode is âsacrificed.â.
cathode ray tube (CRT) A cathode ray tube (CRT) is a specialized vacuumtube in which images are produced when an electron beam strikes aphosphorescent surface. Most desktop computer displays make useof CRTs. The CRT in a computer display is similar to thepicture tube in a television receiver. A cathode ray tube consists of several basiccomponents, as illustrated below. The electron gun generates anarrow beam of electrons.
