konichiva, i had left that question to stndrd integral type yaar,

dx/(a){(b)^.5}

 

a is quadratic,

b is quadratic,

you can solve further by

putting t=1/z and simplifying

then put

 1+z^2=m^2 and got the answer.

 

 

qustn which i had given is my query but you can accept it as challenge too,it a tricky one ,cant solve easily,i had already posted it in coomunity q&a
