<p>Integral of sin^-1[x]dx</p>
<p>in other words, Integral of arcsin[x]dx</p>
<p>can anyone solve this for me?</p>
<p>yes </p>
<p>its xsin^-1(x)+root(1-x^2)</p>
<p>lol, you cheated and looked it up in the table of integrals</p>
<p>haha yeah, does anyone know the way to solve it using an integration technique?</p>
<p>It certainly isn't any of the basic integration techniques covered in most textbooks.</p>
<p>Was that your homework or exam problem?</p>
<p>"It certainly isn't any of the basic integration techniques covered in most textbooks."</p>
<p>whatever teacher uses those kinds of books should be shot.</p>
<p>kevintech: just looking at Malishka's answer can reveal how to solve the problem. Since arcsin(x) reappears in the answer, it's likely that you just use a simple integration by parts.</p>
<p>In this problem, integration by parts does indeed work:</p>
<p>let u = arcsin(x) and dv = dx and the problem is easy.</p>
<p>oh btw- for undergraduate calculus, if you're asked to integrate some function containing an inverse trig function, in 90% of the cases, you'll have to use integration by parts and let u equal the inverse trig function itself.</p>
<p>shoot me too</p>
<p>EDIT: I was wrong in my above post, I found that there is such an exercise in the section "Integration by Parts" in my old textbook. It's been well over a year :)</p>

???
Why are you guys doing finite mathematics on this thread?!</p>
<p>umm i just posted the answer b/c i memorized it, but ya its simple integration by parts.</p>
<p>reality is that after cacl 2 you dont use any other integration in your calc 3 class, atleast i did not. </p>
<p>We only used integration by parts and u-sub and maybe on a very very very rare occasion some trig identity substitiution.... when you go a whole semester without the other types of integration you tend to foreget, imo.</p>
<p>I don't really care anymore since I just took my last Calculus II final last Tuesday. No more integration techniques! [maybe in physics]</p>
<p>UCLA is stupid, i emailed them hypothetically asking how is lack of progression probation viewed from a non ucla email account.</p>
<p>their responce:"please give us your name and student id number so we can assit you better"</p>
<p>MOnkey balls!</p>
<p>uh...what the hell is going on..</p>
<p>Happy bday to me!</p>
<p>YAY</p>
<p>Happy Birthday!</p>
<p>*****, my admissions decision has changed... It has been like 10 days since i notified. It wasn't like this first time i did it.</p>
<p>here is what it says.</p>

<p>This is a good thing because it means they've received your changes and will now begin your reevaluation.</p>
<p>mine changed to that for the second time, dont freak out, no big deal</p>
<p>malishka, was it a positive thing? Did they send u the OKay afterwards?</p>
<p>Lol, whether you get an OK depends on their review of your academics, not Malishka's. Mine changed back to normal after a month (beginning of May to end of May) after they emailed me to let me know that my academic changes did not affect my Fall admission.</p>
