Evaluate the following integrals:
To Find :
Now, let be written as (2x – 4) -1 and split
Therefore ,
=
=
Now solving,
Let = u
dx =
Thus, becomes
Now , =
=
=
=
Now solving,
=
=
Let x – 2 = y dx = dy
Then becomes
Formula Used: =
log |x +
|+ C
Since is in the form of
with change in variable.
Hence =
log |y +
|+ C
= log |y +
|+ C
Now, since x – 2 = y and dx = dy
=
log |(x-2) +
|+ C
Hence =
log |(x-2) +
|+ C
Therefore , =
log |(x-2) +
|+ C
=
log |x - 2 +
|+ C
