 Olathe Dinner is overrated. WILDSTYLE The striploin I just ate was quite delicious actually. TRWBW striploin? is that some foreign word for what? skirt steak? WILDSTYLE skirt steak? Olathe word ? Cale http://en.wikipedia.org/wiki/Strip_steak moeSizlak how in the everloving name of god do you integrate sin(x)*cos(x) ??????????? Cale moeSizlak: -(1/2) cos(x)^2 WILDSTYLE Thank you cale :) moeSizlak what method is that/? TRWBW moeSizlak: what's sin(a+b)? Olathe moeSizlak: Substitution. kilimanjaro let u = sin x, du = cos x dx TRWBW moeSizlak: Cale is right, but you can do it more than one way moeSizlak ok, so then you have the integral of u*du ? Olathe Yes. moeSizlak isnt that like ln u or comething? Olathe Nope. kilimanjaro 1/2 u^2 moeSizlak what is it?oh yeah kilimanjaro moeSizlak, you might want to practice finding derivatives moeSizlak damn, im taking mth 411 probability theory, but i forgot all the lame integral bs from 1st semester kilimanjaro at some point this should just be reflexwhat do you need integrals for? infinite probability spaces? moeSizlak triple integrals actually TRWBW moeSizlak: don't piss off the integral god moeSizlak expected values of 3 random variables kilimanjaro ahhcontinuous I guess Cale You can play "guess the antiderivative", but when you get tired of that, substitution or integration by parts works well. moeSizlak probability x
