The value of   lim_(x→(π/2))    (([(x/2)])/(log (sin x))) = ?  [.]= greatest integer function.
Thevalueoflimxπ2[x2]log(sinx)=?[.]=greatestintegerfunction.

f(x)=[(x/2)]=0 if x is close to (π/2)  so f′(x)=0  g(x)=ln sin x  g′(x)=(1/(tan x))  ((f′(x))/(g′(x)))=0×tan x=0  lim_(x→(π/2)) (([(x/2)])/(ln sin x))=lim_(x→(π/2)) 0×tan x=0
f(x)=[x2]=0ifxisclosetoπ2sof(x)=0g(x)=lnsinxg(x)=1tanxf(x)g(x)=0×tanx=0limxπ2[x2]lnsinx=lim0xπ2×tanx=0
