Evaluate the following integrals:
To Find :
Now, let x - 3 be written as (2x + 3) - and split
Therefore ,
=
= -
Now solving,
Let = u dx =
Thus,becomes
Now , = = ) =
=
Now solving,
can be written as
i.e,
let = y dx = dy
Therefore, can be written as
Formula Used: = log |x +|+ C
Since is of the form with change in variable.
= log |y +|+ C
= log |y +|+ C
Since , x + = y and dx = dy
= log |(x + ) +|+C
Therefore,
= log |x + +|+C
Hence ,
= - = log |x + +|+C
