Dear Anand


If both the functions are algebric then you can take any function as first or second. but you should choose complicated one as first as differentiation is easy. if you have difficulty in some specific example then post it.


 


All the best.

Integration by substitution can be done in this case


eg .  \intf (g(x)) . g'(x) dx


==>   \int f(t) . d(t)                      [ we substitute g(x) as t and (g'(x).dx) as dt ]


solve the integral equations and finally put the value of t.
