∫{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
