				   How to integrate by parts if the
both the functions are of same type.
eg. $\int$uv dx
where u is algebric
and  v is also algebric

										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 .  $\int$f (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.

1/sinx =cosec x or integration of 1/x = ln |x|+c where c is arbitari constant so by using this formula integration of i/sinx is ln |sinx +c|

sorry made a mistake currect answer is 1/sinx =cosec x integration of cosec(x) is ln|cosec x-cot x|+c where c is arbitari constant....

We have Similarly, So if P(x) = a/2 x 2 +bx +c, then and are off opposite sign and hence there must exist a root between the two numbers.

In the listed image can you tell me how beta*gamma = 2 ….. . . .. ??

The value of gamma is still not correct, either printing mistake or you gave me wrong value. The correct value of gamma is below
