in my opinion it must be definite integration
with proper limits that may be u missed
bcoz indefinite integration of this function is not possible in my opinion

first of al we have to convert the log terms in to the form of   ln
the we will use substitution
let
ln(sinx)=t.................1
therefore tanx.dx=dt...............2
from the first equation we can get the value of sinx in therms of t as if
 
sinx=et
 
now get the value of tanx in terms of t
please find out
let the valuse of tanx in terms of t be u.t
 
then 
come bck to the original question
 
it would be something like
 
t.dx
 
now substitute the value of dx from equation.2 completely in terms of t
 
the then integrate to get the answer
 
plz aprve

t.dx
@ it would be a multiple of 2.303
pl don’t forget
