### NY Lost Funds

 stiv2k i dont see anything Steve|Office Keep looking. stiv2k are you expecting me to cancel something out Steve|Office Not as such.Maybe you should consider my questions to be leading questions. What is the connection with u = cos x and my telling you to look at u^2 and u du? stiv2k greathe quitsi still dont get this buggler u/sqrt(1 + u^2) ?look at it for a while and youll know what to do like steve| said stiv2k udui've been looking at it for 10 minutes now buggler you havent done enough differentiation exercises thendo more differentiation before you start integration stiv2k can i ask one favorjust fuckin tell me how you did it, and it will refresh my memory Food man i wish i had you guys during calc2 stiv2k i've done it all i'm reviewing for the finali just need to remember it buggler you can get lost stiv2k i'm willing to take that risk excelblue stiv2k: so, you're stuck on u*du/Sqrt(1+u^2)? stiv2k excelblue: yea excelblue IIRC, you can go directly from that and get an inverse trig function...but you can also do another u-substitutionbut with a different lettertry letting v = (1 + u^2)(that'll get you dv = 2u*du buggler excelblue: great, you give him the answer after what he just said to me... stiv2k ahthat worksbuggler: but his giving me the answer helped in the way i needed excelblue I think he has struggled with this long enough - I'm sure he has lots more similar exercises coming up buggler he has failure coming up excelblue thinking on your own is beneficial only to some extent - after that, a few hints might start to be more usefulhey, that's how I got through Calc 1... don't think I have a problem todayjust as long as it's only for one of them, and not everything buggler ok, i still think starting to swear at a channel helper is not something you should respond to with help straight away stiv2k buggler: my bad Eclipsor excelblue: I wish I had this channel for the majority of calc 1 and not the last week :P
