bobbym, thank you for the tips. I realized after I posted that I'd ommitted the constant of integration and dx. I need to get used to writting everything out.
anonimnystefy, this isn't the first time I've been thrown by an answer in a different form. I guess my problem is in the algebra. What steps can be taken to show that:?
I'm having some trouble with this type of integration problem.
I break it into two parts first:
I solve each and get:
I end up with:
I've been using an online "Integrator" to check my work, and it keeps telling me the answer should be:
I'm not sure if my answer is just plain wrong, or needs to be manipulated somehow, or if the "Integrator" is throwing me off.
I happened across this forum while looking for info on LATEX. I'm studying to be an actuary (career change) and I've found it necessary to be as clear and specific as possible when asking questions. Until about a year ago I've had almost no knowledge of mathematics. I've been diligently studying in my free time starting with basic arithmetic, then algebra, calculus and finally the probability and statistics that I'm going to need. Because I've gone through all of this in such a relatively short amount of time there are some gaps in my understanding of these subjects. I'm excited to find this general Math forum so that I can have some answers to some general math questions!
On a personal level I graduated from college in 2007 (business major). I work for an insurance company and I live near the beach in San Diego, CA. I'd imagine I'll be a heavy presence on here for some time through my exam process
I'm having trouble getting this result when I try to integrate this expression so I have a couple of questions:
1). I'm trying to use integration by parts. Am I on the right track?
2). I've been able to get the result:
and I thought there might be a way to manipulate that into the above given answer, but I'm struggling. Where am I going wrong/what is the next step?
