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.
CRT Cursor Control Mechanism Pad To assist the operation of a cathode ray tube pointer 10 wherein a metal ball is rolled on a hard surface, the disclosed pad may be utilized. A resilient, rubber-like material 12 is bonded or otherwise attached to a hard base material 14 which keeps the rubber-like material flat. The base has four rubber-like pads 16 on the opposite side from the resilient material to refrain the pad from sliding on the surface of a table, for instance.
