How do you integrate ∫x√3+x2dx using trigonometric substitution?
1 Answer
Explanation:
You do not really need a trigonometric substitution here. As:
you can just substitute:
and have:
However if you want to perform a trigonometric substitution, the right substitution when under the square root there is a sum of square is:
In this case we have:
we now use the trigonometric identity:
and have:
Then we note that
To substitute back
so that:
