交流電圧の時間変化が正弦波の時の実効値の求め方についてですが、なぜ写真のような考え方で実効値が求まるのですか？また積分する意味もわからないです。解説おねがいします。 https://detail-infomation.com/rms-of-sine-wave/

正弦波の実効値 VM -VM VRMS 絶対値を求める式 = 0 上式において、 v(wt) = VM sin wt 波形(wt) の実効値VRMS は ひ (wt) を2乗 して平均した値の平方根なので、以下の式で 表されます。 TC 2π 2π →wt 2πT 1 Ső v(wt) ² d (wt) 2πT X = = [² v(wt) ² d (wt) =

写真の問題の2行目のit dose は何を指していますか？

(B) If the discipline of linguistics has so little to be said in its favour, one might wonder how it continues to flourish as widely as it does. It was never the case that all universities contained a linguistics department, and there are probably fewer of them today than there were in the immediate aftermath of the 1960s wave of enthusiasm. But the many linguistics departments that still exist are fairly secure. In the 21st century, decisions about which subjects should be offered in a university are made not in terms of their intellectual solidity but of which will be cost-effective, by attracting a market of student takers. Linguistics departments are well placed there, for two reasons. (Sampson, Geoffrey. 2017. The Linguistics Delusion, Equinox)

Shortly after, hundreds of Jewish visitors, including a far-right MP, ascended the hilltop site, where some danced, waves Israeli flags and bowed down to pray, before being stopped by police. 3. This year's march took place amid an already highly charging atmosphere between Israelis and Palestinians. 4. Special Counsel Robert Mueller concluded that Russia tried to damage Hillary Clinton and help Trump win, as did the bipartisan Senate Intelligence Committee panel that it investigated the election. 5. Much of the trial has focused on a Sept. 2016 meeting in which a lawyer working with the Clinton campaign and a technology executive brought to the FBI about contact between Trump and a major Russian bank.
