stiv2ki dont see anything
Steve|OfficeKeep looking.
stiv2kare you expecting me to cancel something out
Steve|OfficeNot 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?
stiv2kgreat
he quits
i still dont get this
buggleru/sqrt(1 + u^2) ?
look at it for a while and youll know what to do like steve| said
stiv2kudu
i've been looking at it for 10 minutes now
buggleryou havent done enough differentiation exercises then
do more differentiation before you start integration
stiv2kcan i ask one favor
just fuckin tell me how you did it, and it will refresh my memory
Foodman i wish i had you guys during calc2
stiv2ki've done it all i'm reviewing for the final
i just need to remember it
buggleryou can get lost
stiv2ki'm willing to take that risk
excelbluestiv2k: so, you're stuck on u*du/Sqrt(1+u^2)?
stiv2kexcelblue: yea
excelblueIIRC, you can go directly from that and get an inverse trig function...
but you can also do another u-substitution
but with a different letter
try letting v = (1 + u^2)(
that'll get you dv = 2u*du
bugglerexcelblue: great, you give him the answer after what he just said to me...
stiv2kah
that works
buggler: but his giving me the answer helped in the way i needed
excelblueI think he has struggled with this long enough - I'm sure he has lots more similar exercises coming up
bugglerhe has failure coming up
excelbluethinking on your own is beneficial only to some extent - after that, a few hints might start to be more useful
hey, that's how I got through Calc 1... don't think I have a problem today
just as long as it's only for one of them, and not everything
bugglerok, i still think starting to swear at a channel helper is not something you should respond to with help straight away
stiv2kbuggler: my bad
Eclipsorexcelblue: I wish I had this channel for the majority of calc 1 and not the last week :P
