How do you find the integral of #int (x-2)/((x+1)^2+4)#?
you can't use the integral of arctan(x) yet, because the numerator isn't just a constant. to remove the x term from the numerator, you have to use ln(x).
the formula for using ln(x) for integrals: expand the denominator: rewrite now the first integral has the for for this problem, (x+1) will equal the x in the formula, and 2 will equal the a. combining everything: final answer:
you can merge the two C's into a single C because adding any two constants still results in a constant.

To find the integral of (\int \frac{x - 2}{(x + 1)^2 + 4} , dx), you can use the method of partial fraction decomposition followed by a trigonometric substitution.
First, perform partial fraction decomposition to express the integrand as a sum of simpler fractions. Then, use a trigonometric substitution such as (x + 1 = 2\tan(\theta)) to simplify the integral into a form that can be easily integrated. Finally, integrate the resulting expression and substitute back the original variable if necessary.
The steps involved in this process are somewhat involved and may be lengthy to explain fully here. If you need assistance with the detailed steps, I can provide them upon request.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
