∫{1}over{sin^2 x}dx
newline =∫{(sin^2 x+cos^2 x)}over{sin^2 x} dx
newline =∫{sinx sinx+cosx cosx}over{sin^2 x} dx
newline =∫{-(cosx)'sinx+cosx(sinx)'}over{sin^2 x} dx
newline =-∫{(cosx)'sinx-cosx(sinx)'}over{sin^2 x} dx
newline =-∫({cosx}over{sinx})' dx
newline =-{cosx}over{sinx} +C
newline =-{1}over{tanx} +C
文にするとこんな感じ....

まあ、なんのためにUPしたのかと言うと
この公式をばら撒きまくって
間違っていたらだれかが訂正してくれるだろう。
という考えでUPしたので
常識と返って来るということは
この公式は正解ということですかね。
