dan815 · Answer

u substitution

dan815 · Answer

and then parts

dan815 · Answer

do u knoow formula for parts?

dan815 · Answer

you should get e^u(u-1) where u = sqrtx

dan815 · Answer

the fomula for parts comes from Product rule
d/dx UV = V dU/dx + U dV/dx
integrate both sides 
 $$UV = \int\limits_{?}^{?} V du/dx  + \int\limits_{?}^{?}  U dV/dx$$
\int\limits_{?}^{?}  U dV/dx\]  = UV - \int\limits_{?}^{?} V du/dx 
thats how you get 
the formula \int\limits_{?}^{?}  UdV = UV - \int\limits_{?}^{?}  V dU

dan815 · Answer

thats how you get the formula 
Integral U dV = UV - Integral VDu

dan815 · Answer

you should just look up parts integration if u forgot it looks a lot clearer if you just see from a text book
